Generating Functions in $R^{2 n}$ and the Hatcher-Waldhausen map

Thomas Kragh

In this paper, we construct a generating function quadratic at infinity for any exact Lagrangian in $R^{2 n}$ that equals $R^{n}$ outside a compact set. Such a Lagrang…

Normal invariant of nearby Lagrangians via twisted derivative

Mohammed Abouzaid, Daniel Ãlvarez-Gavela, Sylvain Courte +1

Let $L$ and $M$ be closed, connected, smooth manifolds and let $L ↪ T^{*} M$ be an exact Lagrangian embedding. The induced map $L \to M$ is known by earlier work to be a…

Twisted generating functions and the nearby Lagrangian conjecture

We prove that, for closed exact embedded Lagrangian submanifolds of cotangent bundles, the homomorphism of homotopy groups induced by the stable Lagrangian Gauss map vanishes. In p…
