Speaker: Antonio Ioppolo (Università de L'Aquila)
Title: " A taste of polynomial identities"
Abstract: A polynomial identity of an algebra A is a polynomial (in non-commuting variables) vanishing under all evaluations in A. Algebras satisfying at least one of these non-trivial relations are called PI-algebras. The first goal of this talk is to show how it is possible to characterize PI-algebras by means of numerical invariants related to their identities. Along the way we will highlight the combinatorial and analytical aspects of the theory, its connection with invariant theory, representation theory and growth problems. In the last part, we will look at some of the latest developments in this area, when it comes to algebras with additional structure.

Title: "Glimpses from truss theory "
Abstract: Trusses are like affine rings: as a ring is an abelian group with a compatible multiplica-tion, a truss is a torsor (over an abelian group) with a compatible multiplication. Introduced by Brzeziński in 2017 to unify the classical theory of rings with the modern theory of braces, trusses unexpectedly revealed the existence of a previously uncharted territory, whose exploration is not just leading to fascinating discoveries, but it is also shedding new light on groups and rings themselves. This talk would like to be a brief walk in the world of ternary operations to meet heaps, trusses, their modules and their novel heaps of modules.

Title: "New center construction and α-induction for equivariantly braided tensor categories "
Abstract: α-induction is known to be a construction of a modular invariant full Q-system from a chiral Q-system of a conformal net. In this talk, I would like to introduce the equivariant version of this procedure. Indeed, we need a new construction of tensor categories, the neutral double construction, introduced by the speaker. Moreover, I would like to explain the relationship between the neutral double construction and an equivariant version of the center construction, which is also introduced by the speaker.

Title: "$\alpha$-induction for bi-unitary connections. "
Abstract:
The tensor functor called \alpha-induction arises from a Q-system in a
braided unitary fusion category. In the operator algebraic language, it
gives extensions of endomorphism of N to M arising from a subfactor N
\subset M of finite index and finite depth giving a braided fusion category
of endomorphisms of N. We study this \alpha-induction for bi-unitary
connections, which give a characterization of finite-dimensional
nondegenerate commuting squares. We show that the resulting \alpha-induced
bi-unitary connections are flat if we have a local Q-system.
