DESCRIPTION:Speakers: Loic Poulain d'Andecy (Université Reims)\n\nQuiver 
 Hecke algebras\, or KLR algebras\, have been a revolution in the represent
 ation theory of the symmetric group and more generally of Hecke-type algeb
 ras of a type A flavour. They opened the world of graded representation th
 eory for these algebras\, also including the Temperley--Lieb algebra and i
 ts one-boundary generalisation. All this is thanks to the Brundan-Kleshche
 v-Rouquier isomorphism relating KLR algebras and affine Hecke algebras of 
 type A. In this talk I will explain a generalisation of some of these resu
 lts for affine Hecke algebras of type B/C\, involving the so-called orient
 ifold KLR algebras. I will discuss connections with quantum groups and qua
 ntum symmetric pairs and hopefully have time to present a recent applicati
 on to two-boundary Temperley--Lieb algebras (joint work with C. Bowman\, Z
 . Daugherty\, M. de Visscher\, R. Muth).\n\nhttps://math-events.uni-bonn.d
