SMRI Algebra and Geometry Online: Boos -- Advertising symmetric quivers and their representations


SMRI Algebra and Geometry Online
’Advertising symmetric quivers and their representations’
Magdalena Boos (Ruhr-University Bochum)

Thursday 17th June
3:30pm - 5:00pm (AEST)
Online via Zoom

Abstract: We introduce the notion of a symmetric quiver as provided by Derksen and 
Weyman in 2002 and discuss symmetric degenerations in this context (which correspond to 
orbit closure relations in the symmetric representation variety). After motivating our 
particular interest in the latter by presenting connections to group actions in 
algebraic Lie Theory, we explain our main questions: are symmetric degenerations 
induced by "usual" degenerations in the representation variety of the underlying 
quiver? We look at (counter)examples and recent results. This is joint work with 
Giovanni Cerulli Irelli.
