Seminar

Twisted generating functions and the nearby Lagrangian conjecture (I)

Higher algebraic structures in algebra, topology and geometry

05 April 13:30 - 14:30

Sylvain Courte - Université Grenoble Alpes

I will present the nearby Lagrangian conjecture from symplectic topology and some connection with Waldhausen's manifold approach to algebraic K-theory of spaces, as was first discovered by Kragh and developed in a joint work with Abouzaid, Guillermou and Kragh. This goes via the classical notion of generating functions, an early tool in symplectic topology, which relates properties of Lagrangian/Legendrian submanifolds with parametrized Morse theory or pseudo-isotopy theory. If time permits, I will explain how this leads to strong constraints on the stable Lagrangian Gauss map of a nearby Lagrangian.
