Explore a comprehensive lecture by Yan Soibelman from Kansas State University on Cohomological Hall Algebras, Nekrasov Instantons, and Coulomb Branches. Delve into two distinct parts of the talk: first, examine the role of Cohomological Hall algebras in the generalized AGT conjecture, offering a 3-dimensional Calabi-Yau perspective on geometric representation theory results related to moduli spaces of instantons. Then, investigate speculations concerning 3-dimensional gauge theories, focusing on Cohomological Hall algebras and the generalized Riemann-Hilbert correspondence. Gain insights into advanced mathematical concepts and their applications in theoretical physics during this hour-long presentation from the University of Miami.
