SUMMARY:Fukaya categories and higher representation theory
DESCRIPTION:Differential Geometry and Physics Seminar  \nSpeaker: Vivek Shende (Syddansk Universitet & UC Berkeley) \nTitle: Fukaya categories and higher representation theory \nAbstract: I will explain how Lagrangian Floer homology in certain monopole moduli spaces recovers the Khovanov homology and its relatives\, by a description strikingly similar to the Oszvath-Szabo Heegard-Floer theory.  I will also explain how the ‘sectorial descent’ of Fukaya categories can be used to construct Rouquier’s promised monoidal structure on the category of representations of the categorified “positive part” of the quantum group.  This is joint work with Mina Aganagic\, Elise LePage\, and Peng Zhou. \nNote: Location change to Harvard Science Center Room 300H \n

SUMMARY:Strongly adapted contact geometry of Anosov 3-flows
DESCRIPTION:Differential Geometry and Physics Seminar  \nSpeaker: Surena Hozoori (Brandeis) \nTitle: Strongly adapted contact geometry of Anosov 3-flows \nAbstract: We will discuss some recent developments in the contact geometric theory of Anosov 3-flows\, whose roots go back to the works of Mitsumatsu and Eliashberg-Thurston in the mid 1990s. In particular\, we provide a contact geometric characterization of Anosov 3-flows based on interactions with Reeb dynamics\, as well as investigate the basic properties of the resulting geometries. Time permitting\, we will discuss how these results allow one to re-approach some classical questions in Anosov dynamics.

SUMMARY:Gauge theory on Hyperkähler manifolds
DESCRIPTION:Differential Geometry and Physics Seminar  \nSpeaker. Emily Autumn Windes (New Uzbekistan University) \nTitle: Gauge theory on Hyperkähler manifolds \nAbstract: In this talk\, I describe various distinguished classes of connections on Hyperkähler manifolds and their dimensional reductions. Then\, I describe a construction of new examples of Sp(2)-instantons\, primitive HYM connections\, and Spin(7)-instantons with symmetry on the manifold T*CP2. This talk is based on joint work with Jesse Madnick and Izar Alonso.
