DESCRIPTION:Title: Symmetric tensor categories I\nby Pavel Etingof (MIT) as part of ICRA
2020\n\n\nAbstract\nLecture 1: Algebra and representation theory without
vector spaces.\n\nA modern view of representation theory is that it is a s
tudy not just of individual representations (say\, finite dimensional repr
esentations of an affine group or\, more generally\, supergroup scheme G o
ver an algebraically closed field k ) but also of the category Rep(G) form
ed by them. The properties of Rep(G) can be summarized by saying that it i
s a symmetric tensor category (shortly\, STC) which uniquely determines G
. A STC is a natural home for studying any kind of linear algebraic struct
ures (commutative algebras\, Lie algebras\, Hopf algebras\, modules over t
hem\, etc.)\; for instance\, doing so in Rep(G) amounts to studying such s
tructures with a G -symmetry. It is therefore natural to ask: does the stu
dy of STC reduce to group representation theory\, or is it more general? I
n other words\, do there exist STC other than Rep(G) ? If so\, this would
be interesting\, since algebra in such STC would be a new kind of algebra\
, one “without vector spaces”. Luckily\, the answer turns out to be
“yes”. I will discuss examples in characteristic zero and p>0 \, and a
lso Deligne’s theorem\, which puts restrictions on the kind of examples
one can have.\n

spaces constructed from data and infer the ‘‘shape’’ of the data
from topological invariants. The term ‘’persistent’’ refers to the
fact that the construction of these spaces usually depends on one or more
parameters\, and in order to obtain information about the data in a stabl

nvariants relate across scales. This naturally leads to a representation o
f a totally ordered set.\n\nIn this first lecture I will motivative persis

, and state foundational results.\n\nLecture 2: Multiparameter persistent
homology part 1\n\nMultiparameter persistent homology is a vibrant subfiel
d of topological data analysis which has attracted much attention in recen
t years. It has become evident that the transition from a single to multip
le parameters comes with significant computational and mathematical challe
nges. At the level of representation theory\, this can be understood by th
e fact that one is studying representations of a partially ordered set of
wild representation type.\n\nIn this lecture we shall identify settings fo

DESCRIPTION:Title: Symmetric tensor categories II\nby Pavel Etingof (MIT) as part of ICR
A 2020\n\n\nAbstract\nLecture 2: Representation theory in non-integral ran
k.\n\nExamples of symmetric tensor categories over complex numbers which a
re not representation categories of supergroups were given by Deligne-Miln
e in 1981. These very interesting categories are interpolations of represe
ntation categories of classical groups GL(n) \, O(n) \, Sp(n) to arbitrary
complex values of n . Deligne later generalized them to symmetric groups
and also to characteristic p \, where\, somewhat unexpectedly\, one needs
to interpolate n to p -adic integer values rather than elements of the gro
und field. I will review some of the recent results on these categories an
d discuss algebra and representation theory in them.\n

DESCRIPTION:Title: Symmetric tensor categories III\nby Pavel Etingof (MIT) as part of I
CRA 2020\n\n\nAbstract\nLecture 3. Symmetric tensor categories of moderate
growth and modular representation theory.\n\nDeligne categories discussed
in Lecture 2 violate an obvious necessary condition for a symmetric tenso
r category (STC) to have any realization by finite dimensional vector spac
es (and in particular to be of the form Rep(G) ): for each object X the le
ngth of the n -th tensor power of X grows at most exponentially with n . W
e call this property “moderate growth”. So it is natural to ask if the
re exist STC of moderate growth other than Rep(G) . In characteristic zero
\, the negative answer is given by the remarkable theorem of Deligne (2002
)\, discussed in Lecture 1. Namely Deligne’s theorem says that a STC of
moderate growth can always be realized in supervector spaces. However\, in
characteristic p the situation is much more interesting. Namely\, Deligne
’s theorem is known to fail in any characteristic p>0 . The simplest exo
tic symmetric tensor category of moderate growth (i.e.\, not of the form R
ep(G) ) for p>3 is the semisimplification of the category of representatio
ns of Z/p \, called the Verlinde category. For example\, for p=5 \, this c
ategory has an object X such that X2=X+1 \, so X cannot be realized by a v
ector space (as its dimension would have to equal the golden ratio). I wil
l discuss some aspects of algebra in these categories\, in particular fail
ure of the PBW theorem for Lie algebras (and how to fix it) and Ostrik’s
generalization of Deligne’s theorem in characteristic p . I will also d
iscuss a family of non-semisimple exotic categories in characteristic p co
nstructed in my joint work with Dave Benson and Victor Ostrik\, and their
relation to the representation theory of groups (Z/p)n over a field of cha
racteristic p .\n

DESCRIPTION:Title: The wall-chamber structures of the real Grothendieck groups\nby Sota
Asai (Osaka University) as part of ICRA 2020\n\n\nAbstract\nFor a given f
inite-dimensional algebra A over a field\, stability conditions introduced
by King define the wall-chamber structure of the real Grothendieck group
K0(projA)R \, as in the works of Br"{u}stle–Smith–Treffinger and Bridg
eland. In this talk\, I would like to explain my result that the chambers
in this wall-chamber structure are precisely the open cones associated to
the basic 2-term silting objects in the perfect derived category. As one o
f the key steps\, I introduced an equivalence relation called TF equivalen
ce by using numerical torsion pairs of Baumann–Kamnitzer–Tingley. If t
ime permits\, I will give some further results which were obtained in the
ongoing joint work with Osamu Iyama.\n

DESCRIPTION:Title: Bases of cluster algebras\nby Fan Qin (ICRA 2020 Award Winner) (Shan
ghai Jiao Tong University) as part of ICRA 2020\n\n\nAbstract\nOne of Fomi
n and Zelevinsky’s main motivations for cluster algebras was to study th
e dual canonical bases. Correspondingly\, it had been long conjectured tha
t the quantum cluster monomials (certain monomials of generators) belong t
o the dual canonical bases up to scalar multiples. Geiss-Leclerc-Schröer
proved an analogous statement that the cluster monomials belong to the dua
l semi-canonical bases\, which are examples of generic bases.\n\nIn a geom
etric framework for cluster algebras\, Fock and Goncharov expected that cl
uster algebras possess bases with good tropical properties.\n\nIn this tal
k\, we consider a large class of quantum cluster algebras called injective
-reachable (equivalently\, there exists a green to red sequence). We study
their tropical properties and obtain the existence of generic bases. Then
we introduce the (common) triangular bases\, which are Kazhdan-Lusztig ty
pe bases with good tropical properties. We verify the above motivational c
onjecture in full generality and\, by similar arguments\, a conjecture by
Hernandez-Leclerc about monoidal categorification.\n
