Gaston will give the Seminar’s twelfth and final talk for Semester 1 tomorrow afternoon 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 firstname.lastname@example.org. Abstract: In this talk, I will give an attempt to motivate further the study of perverse sheaves. I will give some classical homology examples to put ourselves in the perspective of the mathematicians in the 70’s, before the theory of intersection homology was discovered. Time and date: 2 pm Wednesday 30 June.
