Derived categories in Algebraic Geometry and Representation Theory

Short course
by  Luisa Fiorot  (Dipartimento di Matematica ”Tullio Levi-Civita”, Padova, Italy)

Introduction to derived categories: abelian categories, functors, natural transformations, triangulated categories, category up to homotopy and derived category. Examples. 

16th June 2023
Examples of abelian categories: coherent and quasi-coherent sheaves on a separated quasi compact scheme. Coherent sheaves on a complex manifold. Category of modules on a ring. 

19th June 2023
Derived functors. Cohomology of sheaves. Derived direct image and inverse image of quasi-coherent sheaves and their adjunction formula. 

20th June 2023
Torsion pairs in abelian categories and t-structures in triangulated categories. Examples. 

21st June 2023
Beilinson theorem: equivalence of the derived category of coherent sheaves on the projective line and the derived category of representations of the Kronecker quiver.

43rd Conference on Stochastic Processes and their Applications

SPA Conferences are organised under patronage of the Bernoulli Society and can justifiably be regarded as the most important international scientific meeting on the theory and applications of stochastic processes.
They are held annually except for the years when the World Congress in Probability and Statistics takes place.

IST, University of Lisbon, 24-28 July 2023.
