This is a mixture of survey article and research announcement. We discuss instanton Floer homology for 3 manifolds with boundary. We also discuss a categorification of the Lagrangian Floer theory using the unobstructed immersed Lagrangian correspondence as a morphism in the category of symplectic manifolds. During the year 1998–2012, those problems have been studied emphasizing the ideas from analysis such as degeneration and adiabatic limit (instanton Floer homology) and strip shrinking…

Around 1988, Floer introduced two important theories: instanton Floer homology as invariants of 3-manifolds and Lagrangian Floer homology as invariants of pairs of Lagrangians in symplectic

We study the equivariant disc potentials for immersed SYZ fibers in toric Calabi-Yau manifolds. The immersed Lagrangians play a crucial role in the partial compactification of the SYZ mirrors.
In this paper we construct a 2-functor from the unobstructed immersed Weinstein category to the category of all filtered A infinity categories. We consider arbitrary (compact) symplectic manifolds

Lagrangian Floer cohomology associates to a pair of Lagrangian manifolds a chain complex whose differential counts pseudoholomorphic strips with boundary values in the given Lagrangians. These form a
We introduce Floer homology for transversely intersecting Lagrangian immersions L and L′ in a symplectic manifold (X, ω). By using this homology, if π2(X, L) = 0 and L′ is the image of L under a
We study nonlocal Lagrangian boundary conditions for anti-self-dual instantons on 4-manifolds with a space-time splitting of the boundary. We establish the basic regularity and compactness properties
