Will Hardesty will give the Seminar’s fifth 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. Title: Recollement Abstract: In tomorrow’s talk I will first define the right adjoint of proper pushforward (or "upper-shriek" functor) for locally closed inclusions. I will then explain how this leads to recollement or "gluing theory" for t-structures. And if time permits, I will discuss Poincare-Verdier duality. Time and date: 2 pm, Wednesday 21 April Seminar website: https://www.maths.usyd.edu.au/u/ciappara/SAS.html
