Lecture series on Hodge Theory

Thursday, 12 Oct. 11.30-1.00


Venue: Ramanujan Hall

Host: Sudarshan Gurjar

Title: Kahler condition and its consequences
Abstract: These are part of an ongoing series of lectures on the basics of Hodge theory. We will discuss the Kahler condition, and its consequences (Kahler identities, etc.).

Topology and Related Topics Seminar

Thursday, 12  October  2023, 2:30 pm


Venue: 215

Host: Rekha Santhanam

Speaker:  Omkar Javadekar

Affiliation: IIT Bombay

Title: A review of derived category and related topics 


Abstract: In this talk, we will see the construction of localization of a category with respect to an arbitrary class of morphisms, and define the derived category using localization. We will sketch the proof of the fact that the homotopy and derived categories are triangulated. Along the way, we will also try to revise the example of projective model structure on the category Ch(R) of chain complexes of modules over a ring R. We will then define the notion of support for objects of the derived category D(R), and end by stating the theorem of Hopkins-Neeman for small R-complexes.
