The fundamental group of a rigid Lagrangian cobordism

Abstract

In this article we extend the construction of the Floer fundamental group to the monotone Lagrangian setting and use it to study the fundamental group of a Lagrangian cobordism W(C×M,ωstω)W\subset (\mathbb{C}\times M, \omega_{st}\oplus\omega) between two Lagrangian submanifolds L,L(M,ω)L, L'\subset ( M, \omega). We show that under natural conditions the inclusions L,LWL,L'\hookrightarrow W induce surjective maps π1(L)π1(W)\pi_{1}(L)\twoheadrightarrow\pi_{1}(W), π1(L)π1(W)\pi_{1}(L')\twoheadrightarrow\pi_{1}(W) and when the previous maps are injective then WW is an h-cobordism.
