 >Symmetric tensor categories I</a>\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

 al (co-)homology will be assumed.\n\nLecture 1: Persistent homology in a s

 g field of topological data analysis. The key idea is to study topological
  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
 e and robust way\, it is crucial to consider how the family of resulting i
 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
 tent homology in a single parameter\, introduce the necessary terminology\
 , 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
 r which the theory in the first lecture generalizes to more general posets
 . Of particular interest is level-set zigzag persistent homology.\n\nLectu

 >Symmetric tensor categories II</a>\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

 ">Symmetric tensor categories III</a>\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

 ">Bases of cluster algebras</a>\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

 ">Expressive curves</a>\nby Sergey Fomin as part of ICRA 2020\n\n\nAbstrac
 t\nWe call a real plane algebraic curve C expressive if its defining polyn
 omial has the smallest number of critical points allowed by the topology o
 f the set of real points of C. We give a necessary and sufficient criterio
 n for expressivity (subject to a mild technical condition)\, describe seve
 ral constructions that produce expressive curves\, and relate their study 
 to the combinatorics of plabic graphs\, their quivers and links. This is j
 oint work with E. Shustin.\n
