Lagrangian cobordisms and K-theory of symplectic bielliptic surfaces
Lagrangian cobordisms and K-theory of symplectic bielliptic surfaces
We consider a family of closed symplectic manifolds 4-manifolds which we call symplectic bielliptic surfaces and study its Lagrangian cobordism group of weakly-exact Lagrangian G-branes (that is, Lagrangians equipped with a grading, a Pin structure and a G-local system); relations come from Lagrangian cobordisms satisfying a tautologically unobstructedness-type condition, also …
