DESCRIPTION:Title: O
n the irrationality of certain 2-adic zeta values\nby Li Lai (Tsinghua
University) as part of PKU/BICMR Number Theory Seminar\n\nLecture held in
Room 77201\, BICMR.\n\nAbstract\nLet $\\zeta_2(\\cdot)$ be the Kubota-Leo
poldt $2$-adic zeta function. We prove that\, for every nonnegative intege
r $s$\, there exists an odd integer $j$ in the interval $[s+3\,3s+5]$ such
that $\\zeta_2(j)$ is irrational. In particular\, at least one of $\\zeta
_2(7)\,\\zeta_2(9)\,\\zeta_2(11)\,\\zeta_2(13)$ is irrational.\n\nOur appr
oach is inspired by the recent work of Sprang. We construct explicit ratio
nal functions. The Volkenborn integrals of the (higher order) derivatives
of these rational functions produce good linear combinations of $1$ and $2
$-adic Hurwitz zeta values. The most difficult step is to prove that certa
in Volkenborn integrals are nonzero\, which is resolved by careful manipul
ation of the binomial coefficients.\n\nZoom number: 743 736 2326\n\nPasswo

DESCRIPTION:Title: S
ome satisfactory and unsatisfactory aspects of the dual groups for central
covers\nby Fan Gao (Zhejiang University) as part of PKU/BICMR Number
Theory Seminar\n\nLecture held in Room 77201\, BICMR.\n\nAbstract\nWe cons
ider finite degree central covers of a linear reductive group in the local
setting. Using some examples as the highlights\, we will explain the dual
group of such a central cover\, and illustrate how much it captures the r
epresentation-theoretic information of the central cover\, and also how mu
ch it fails for the same purpose. We concentrate on two aspects of a repre
sentation: formal degree and wavefront set.\n\nZoom number: 743 736 2326\n

437362326?pwd=UXd3RzBiUWZNK2Vhdm05R0c5VlJEUT09\nLecture held in Room 77201
\, BICMR.\n\nAbstract\nWe will discuss a $p$-adic cohomology theory for ri
gid analytic varieties with overconvergent structure (dagger spaces) over
a local field of characteristic $p$. After explaining the motivation\, we
will define a site (Robba site) and discuss its basic properties.\n\nFor o

ematik) as part of PKU/BICMR Number Theory Seminar\n\nLecture held in Room
77201\, BICMR.\n\nAbstract\nIn this talk I will introduce different categ
ories of $p$-adic representations in the framework of condensed mathematic
s. We give different geometric interpretations to them\, construct explici
t adjunctions that serve to compare cohomology theories\, and see an appli
cation to $p$-adic categorical local Langlands for $\\mathrm{GL}_1$.\n\nOn
