Double-point enhanced GRID invariants and Lagrangian cobordisms
Double-point enhanced GRID invariants and Lagrangian cobordisms
We define an invariant of Legendrian links in the double-point enhanced grid homology of a link, and prove that it obstructs decomposable Lagrangian cobordisms in the symplectization of the standard contact structure on $\mathbb R^3$.
