Student Algebra Seminar: Wiggins -- Perverse sheaf examples

Giulian Wiggins will give the Seminar’s eighth talk for Semester 1 tomorrow morning on
Zoom.  Please find the details below.  Anyone who would like to attend the talk or join
the mailing list is warmly invited to e-mail ciappara@maths.usyd.edu.au.  

Abstract: We compute table of stalks for some perverse sheaves on the nilpotent cone in
sl_2 and sl_3.  We will introduce some techniques for doing this, such as Deligne’s
construction of intersection complexes, and an application of the decomposition
theorem.  

Time and date: 11 am Tuesday 11 May.
