DESCRIPTION:Title:
A p-adic Riemann-Hilbert functor and applications\nby Bhargav Bhatt (U
niversity of Michigan) as part of Recent Advances in Modern p-Adic Geometr
y (RAMpAGe)\n\n\nAbstract\nI will discuss an ongoing project (joint with J
acob Lurie) aiming to construct a p-adic Riemann-Hilbert functor\, attachi
ng coherent objects to constructible sheaves (with coefficients in F_p\, Z
_p or Q_p) on a compact algebraic variety over a p-adic field. I'll focus
on the case of F_p-coefficients\, which leads to a solution of some old qu
estions in commutative algebra.\n

DESCRIPTION:Title:
A p-adic transcendence criterion for CM Galois representations\nby Sea
n Howe (University of Utah) as part of Recent Advances in Modern p-Adic Ge
ometry (RAMpAGe)\n\n\nAbstract\nWe show that a crystalline Galois represen
tation with rational de Rham lattice admits a slope filtration with abelia
n isoclinic subquotients. As a corollary\, we find that a $p$-divisible gr
oup over $\\mathcal{O}_{\\mathbb{C_p}}$ has complex multiplication if and
only if it can be defined over a complete discretely valued subfield and i
ts Hodge-Tate filtration is algebraic -- this is a $p$-adic analog of clas
sical transcendence results for complex abelian varieties due to Schneider
\, Cohen\, and Shiga-Wolfart. More generally\, we characterize the special
points of the diamond moduli of mixed-characteristic local shtuka with on
e paw as those with algebraic Hodge-Tate and de Rham periods. The correspo
nding archimedean transcendence results for Shimura varieties fit into a b
roader framework of bialgebraicity that plays an important role in the And
re-Oort conjecture\, and\, time permitting\, we discuss some ideas of what
this might look like in the $p$-adic setting.\n

stract\nÉtale cohomology of $\\mathbf{F}_p$-local systems does not behav

thbf{F}_p$-cohomology of the 1-dimensional closed unit ball is infinite. H
owever\, it turns out that things are much better for proper p-adic rigid-
analytic spaces. For example\, Scholze used perfectoid spaces to show that
proper p-adic rigid-analytic spaces have finite cohomology for any $\\mat
hbf{F}_p$-local system. Based on Gabber's idea\, I will introduce the conc
ept of almost coherent sheaves and use it to “localize” (in an appropr
iate sense) some problems in the étale cohomology of rigid-analytic space
s. For example\, this theory (together with perfectoid spaces) can be used
to give a "new" proof of the finiteness theorem and a proof of Poincaré
duality for p-torsion coefficients on smooth and proper p-adic rigid-analy

\, and the latter has been redeveloped and expanded recently by Boxer and
Pilloni to incorporate higher coherent cohomology. Our work gives a new pr

On the Cohomology of Moduli of Mixed Characteristic Shtukas\nby Richar

d their moduli. These generalize the Lubin-Tate tower and other Rapoport-Z
ink spaces. Under the Kottwitz conjecture\, the cohomology of these space
s are expected to realize the local Langlands correspondence. The data de
fining these spaces involve cocharacters of a Lie group\; when the cochar
acter is minuscule\, we recover classical Rapoport-Zink spaces. In the ca
se of $\\mathrm{GL}_n$\, we show that the Kottwitz conjecture for general
cocharacters can be reduced to the minuscule case. This depends on a geom

t\nAbstract: Let $K$ be a $p$-adic field. Let $\\rho$ be an $n$-dimensiona
l continuous absolutely irreducible mod $p$ representation of the absolute
Galois group of $K$. The Kisin variety is a projective scheme which param
etrizes the finite flat group schemes over the ring of integers of $K$ wit
h generic fiber $\\rho$ satisfying some determinant condition. The connect
ed components of the Kisin variety is in bijection with the connected comp
onents of the generic fiber of the flat deformation ring of $\\rho$ with g
iven Hodge-Tate weights. Kisin conjectured that the Kisin variety is conn
ected in this case. We show that Kisin's conjecture holds if $K$ is total
ly ramified with $n=3$ or the determinant condition is of a very particula
r form. We also give counterexamples to show Kisin's conjecture does not
hold in general. This is a joint work with Sian Nie.\n\nPlease note that t

DESCRIPTION:Title: Compatibility of the Fargues-Scholze and Gan-Takeda Local Langlands Corre
spondences\nby Linus Hamann (Princeton) as part of Recent Advances in
Modern p-Adic Geometry (RAMpAGe)\n\n\nAbstract\nIn upcoming work\, Fargues
and Scholze construct a candidate for a general local Langlands correspon
dence\, \nassociating to a smooth irreducible representation of a connect
ed reductive group $G/\\mathbf{Q}_{p}$ a continuous semisimple Weil parame
ter\, using the action of excursion operators\non the moduli space of $G$-
bundles on the Fargues-Fontaine curve. It is a natural question to ask whe
ther this correspondence is compatible with known instances of the local L
anglands correspondence after semi-simplification. For $G = \\mathrm{GL}_{
n}$\, this compatibility is deduced from the fact that correspondence of H
arris-Taylor is realized in the cohomology of the Lubin-Tate tower at infi
nite level\, via its interpretation as a moduli space of mixed characteris
tic shtukas. For $G = \\mathrm{GSp}_{4}$ or its inner form $\\mathrm{GU}_{
2}(D)$\, there is a local Langlands correspondence constructed by Gan-Take
da and Gan-Tantono\, respectively. We will discuss upcoming work related t
o proving compatibility in this case. Similar to the case of $\\mathrm{GL}
_{n}$\, this involves realizing this local Langlands correspondence in the
cohomology of the local Shimura varieties at infinite level associated wi
th these groups. We do this by applying basic uniformization of these loca
l Shimura varieties due to Shen\, as well as results on Galois representat
ions in the cohomology of the relevant global Shimura varieties due to Sor
ensen and Kret-Shin. After proving this compatibility\, we employ various
new ideas from the geometry of the Fargues Scholze correspondence to obtai
n a complete description of the $\\rho$-isotypic part of the cohomology of
this local Shimura variety at infinite level\, where $\\rho$ is a represe
ntation of $G$ with supercuspidal Gan-Takeda or Gan-Tantono parameter\, th

y Tony Feng (MIT/IAS) as part of Recent Advances in Modern p-Adic Geometry
(RAMpAGe)\n\n\nAbstract\nLaﬀorgue and Genestier-Laﬀorgue have constru
cted the global and (semisimpliﬁed) local Langlands correspondences for
arbitrary reductive groups over function ﬁelds. I will explain some rece
ntly established properties of these correspondences regarding base change
functoriality: existence of transfers for mod $p$ automorphic forms throu
gh $p$-cyclic base change in the global correspondence\, and Tate cohomolo
gy realizes $p$-cyclic base change in the mod $p$ local correspondence. In
particular\, the local statement verifies a conjecture\nof Treumann-Venka
tesh. The proofs combine Lafforgue’s theory with equivariant localizatio
n arguments for shtukas as well as recent advances in modular representati
on theory\, namely parity sheaves and Smith-Treumann theory. Compared with
previous iterations of the talk\,\nthis time the talk will emphasize the
role of the new representation-theoretic tools\, during the extra 20 minut

atisfies the valuative criterion for properness was first asked by Coleman
and Mazur in 1998 and settled by Diao and Liu in 2016 using deep\, powerf
ul Galois-theoretic machinery. We will discuss a new proof which is short
and explicit and uses no Galois theory. Instead we adapt an earlier method
of Buzzard and Calegari based on elementary properties of overconvergent
modular forms\, for which we have to extend Pilloni's geometric constructi
on of overconvergent forms of arbitrary weight farther into the supersingu
lar locus. We will also discuss generalizations in progress.\n

ct\nLet $p$ be an inert prime in a totally real field $F$ for simplicity.
Using the method of analytic continuation\, Kassaei proved a classicality
theorem: an overconvergent Hilbert $U_p$-eigenform is automatically classi
cal when the slope is small compared to the weights. In analogy to overcon
vergent forms\, which are defined over a strict neighborhood of the zero l
ocus of the Hasse invariant\, one can define partially classical overconve
rgent forms as defined over a strict neighborhood of the zero locus of a s
ub-collection of partial Hasse invariants. Under a weaker small slope cond
ition depending on the relevant weights\, we show that an overconvergent $
U_p$-eigenform is partially classical.\n

gh there are plenty of non-de Rham representations of the Galois group of
$K$\, it turns out that for any smooth variety $X$ over $K$ and a $\\overl
ine{\\mathbf{Q}}_p$-local system $L$ on $X$ such that the restriction of $
L$ to $X_{\\overline{K}}$ is irreducible\, there exists a character of the
Galois group of $K$ such that twisting by this character turns $L$ into a
de Rham local system. In particular\, for a geometrically irreducible $\\
overline{\\mathbf{Q}}_p$-local system on a smooth variety over a number fi
eld\, the associated projective representation of the fundamental group au
tomatically satisfies the assumptions of the relative Fontaine-Mazur conje
cture.\n\nThe proof uses $p$-adic Riemann-Hilbert correspondence in the fo

DESCRIPTION:Title: The ramification of p-adic representations coming from geometry\nby J
oe Kramer-Miller (UC Irvine) as part of Recent Advances in Modern p-Adic G
eometry (RAMpAGe)\n\n\nAbstract\nThe purpose of this talk is to explain a
geometric analogue of Sen's classical theorem\, which describes the close
relationship between $p$-adic Lie filtrations and ramification filtrations
for $p$-adic fields. Let $X$ be a smooth variety over a perfect field $k$
with characteristic $p>0$\, let $D\\subset X$ be a reduced divisor with s
mooth normal crossings\, and let $U=X\\backslash D$. Consider a continuous
representation $\\rho:\\pi_1(U) \\to GL(\\Z_p)$\, which gives rise to an
$p$-adic Lie tower of \\'etale covers $U_n \\to U$. We may associate to ea
ch cover a Swan divisor $sw(U_n/U)$\, supported on $D$\, using the ramific
ation filtration of Abbes-Saito. In general\, the growth of these divisors
can be arbitrarily wild. Instead\, we restrict ourselves to representatio
ns that are ordinary geometric (e.g. $\\rho$ arises as the $p$-adic Tate m
odule of a family of ordinary Abelian varieties). Our main result states t
hat for $\\rho$ ordinary geometric\, there exists integers $c_1>c_0>0$ suc
h that $c_1p^{2n} D > sw(U_n/U) > c_0 p^{2n}D$. This says that even though
$\\rho$ has infinite monodromy\, the Swan conductors $sw(U_n/U)$ grow as
`slowly as possible'.\n

DESCRIPTION:Title: $p$-adic six functors on diamonds\nby Lucas Mann (Bonn) as part of Re
cent Advances in Modern p-Adic Geometry (RAMpAGe)\n\n\nAbstract\nMotivated
by $p$-adic Poincaré duality in rigid geometry\, we develop a $p$-adic s
ix functor formalism on rigid varieties\, or more generally for diamonds.
This is achieved by defining a category of "quasi-coherent $\\mathcal{O}_X
^+/p$-modules" on a diamond $X$ and then using the recent development of a
quasi-coherent 6-functor formalism on schemes by Clausen-Scholze to obtai
n a similar 6-functor formalism on diamonds. One easily deduces the desire
d p-adic Poincaré duality on a smooth proper rigid variety $X$ in mixed c
haracteristic\, noting that by Scholze's primitive comparison theorem\, $\
\mathbb F_p$-cohomology on $X$ can be computed via cohomology of the sheaf
$O_X^+/p$. Of course\, our p-adic 6-functor formalism allows for many mor
e potential applications\; for example\, we expect to gain new insights in
the $p$-adic Langlands program.\n

ost fundamental results in the study of étale cohomology of rigid analyti

es a canonical isomorphism between the cohomology of an algebraizable rigi
d analytic variety and the cohomology of the nearby cycle. \nI will discus
s a generalization of this comparison result to the relative case: For an
algebraizable morphism\, the compactly supported higher direct image sheav
es are identified\, up to replacing the target by a blowup\, with a genera
lization of the nearby cycle cohomology\, which is given by the theory of
nearby cycles over general bases. \nThis result can be used to show the ex

n\nAbstract\n(work in progress with Michael Groechenig)\nIf $X$ is smooth

smooth projective over the algebraic closure $k$ of finite field\, and d
oes not have non-trivial differential forms\, one may ask whether all conv
ergent isocrystals have finite monodromy. This is true if $X$ lifts to $W(
