Explore the concept of ambidexterity in the second lecture of a series on Dualities in Topology and Algebra. Delve into advanced mathematical topics as presented by Neil Strickland at the International Centre for Theoretical Sciences. Gain insights into the connections between algebraic topology, commutative algebra, and modular representation theory of finite groups. Examine duality phenomena and classification problems in tensor-triangulated categories. Discover how concepts from commutative algebra and algebraic geometry have been applied to modular representation theory and stable homotopy category. Learn about Grothendieck duality theory, Gorenstein rings and schemes, and their generalizations of classical Poincaré duality for manifolds. Investigate the classification of thick and localising subcategories of triangulated categories and the computation of their spectra. Enhance your understanding of cohomological support varieties and their development in modular representation theory. Read more
