DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TRAC/4/">Inf
 initesimal semi-invariant pictures</a>\nby Eric Hanson as part of The TRAC
  Seminar - Théorie de Représentations et ses Applications et Connections
 \n\n\nAbstract\nSemi-invariant pictures (or wall and chamber structures) a
 rise naturally when considering stability conditions for finite dimensiona
 l algebras. For algebras which are not tau-tilting finite\, these semi-inv
 ariant pictures contain accumulation points. In this talk\, we describe a 
 new semi-invariant picture which captures the local structure near such an
  accumulation point. For tame hereditary algebras\, we further show that t
 his new semi-invariant picture can be described (both geometrically and vi
 a tau-tilting theory) from those of certain Nakayama algebras. This is joi
 nt work with Kiyoshi Igusa\, Moses Kim\, and Gordana Todorov.\n
