Non-decomposable Lagrangian cobordisms between Legendrian knots

Symplectic Geometry 2025-11-14 v2

Abstract

For a given g>0g>0, we construct a family of non-decomposable Lagrangian cobordisms of genus gg between (stabilized) Legendrian knots in the standard contact three-sphere. The main technique we use to obstruct decomposability is based on Livingston's estimates.
