Research Abstract

It is known that Lagrangian Floer cohomology can not be defined for general Lagrangian submanifolds, because of presence of bubbling off phenomena of holomorphic maps from 2-disc. We constructed a certain homotopy algebra, so called a filtered A infty algebra, associated to each Lagrangian submanifold by using holomorphic maps from 2-disc, and established the obstruction theory and deformation theory based on the algebra. We applied our general theory to the case of toric manifolds and obtained many concrete new results in symplectic geometry.
