===========================

Venue: Ramanujan Hall, Department of Mathematics

Host:  Rekha Santhanam

Speaker: Priyanka Magar

Affiliation: IIT Bombay

Title: A brief introduction to the stable homotopy category

Abstract:

 The talk will begin with some stable phenomenon that guides us to the Spanier-Whitehead category, which has its own interesting properties. Next, we'll explore how the Brown representability theorem brings in the idea of Spectra and, as a consequence, gives rise to the stable homotopy category.
