# Student Algebra Seminar: Hone -- Constructibility and the perverse t-structure

Chris Hone will give the Seminar’s sixth 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 will introduce the notions of stratifications and constructibility of
sheaves, and give the constructibility theorem, that for our spaces, constructible
sheaves are closed under the functors we are used to.  We will then discuss the perverse
t-structure from 3 points of view, and possibly see an example if there’s time.

Time and date: 11 am Tuesday 27 April
