Title:

BPS phases and fortuity in higher spin holography

Abstract:

I will explain the large N BPS phases of the ABJ vector Chern-Simons model dual to a higher spin gravity, from the saddle points of its index. Their physical aspects are discussed from the viewpoint of trace relations and fortuitous operators. I will compare them with the AdS string theory and its black holes.

      Nonabelian Hodge theory for stacks and BPS cohomology | BIMSA AG Seminar

      AbstractIf C is a smooth projective complex curve, the nonabelian Hodge correspondence gives adiffeomorphism between the coarse moduli space of degree d rank r semistable Higgs bundles onC, and r-dimensional d-twisted representations of the fundamental group of the underlying Riemannsurface of C. lf r and d are not coprime, there are strictly semistables with nontrivial stabilizers, andit perha...

      Geometric Representation Theory Seminar | Maulik-Okounkov Lie algebras and BPS Lie algebras

      Abstract:The Maulik-Okounkov (MO) Lie algebra associated to a quiver Q controls the R-matrix formalism developed by Maulik and Okounkov in the context of (quantum) cohomology of Nakajima quiver varieties. On the other hand, the BPS Lie algebra originates from cohomological DT theory, and in particular from the theory of cohomological Hall algebras associated to 3 Calabi-Yau categories. In this...
