Mathematical Physics and Algebraic Geometry Seminar Speaker: Ju Tan (Boston University) Title: Mirror Construction for Nakajima Quiver Varieties Abstract: Quiver possesses a rich representation theory. On the one hand, it exhibits a deep connection with instantons and coherent sheaves as illuminated by the ADHM construction and the works of many others. On the other hand, […]

Mathematical Physics and Algebraic Geometry Seminar Speaker: Fabian Ruehle (Northeastern University) Title: Bounds and Dualities of Type II Little String Theories Abstract: The goal of this seminar is to introduce Type II Little String Theories (LSTs), which are six-dimensional supersymmetric QFTs. We explore how to geometrically engineer these theories within the context of M-/F-theory (top-down) as well […]

Mathematical Physics and Algebraic Geometry Seminar Speaker: Tom Scanlon, UC Berkeley Title: (Un)likely intersections Abstract: The Zilber-Pink conjectures predicts that for an ambient special variety  (such as an abelian variety or a Shimura variety), if   is an irreducible algebraic subvariety which is not contained a proper special subvariety of  (e.g. a proper algebraic subgroup in the abelian variety case […]

Mathematical Physics and Algebraic Geometry Seminar Speaker: Qianyu Hao, University of Geneva Title: A new construction of c = 1 conformal blocks Abstract: The Virasoro conformal blocks are very interesting since they have many connections to other areas of math and physics. For example, when c = 1, they are related to tau functions of Painlevé equations. I will first explain what […]

Mathematical Physics and Algebraic Geometry Seminar Speaker: Tobias Ekholm, Uppsala University Title: Skein valued curve counts for the topological vertex and knot conormals Abstract: Combining the invariance of holomorphic curve counts in the skein module with a study of holomorphic curves at infinity of the vertex we find three simple skein operator polynomials that annihilates […]
