Localization of Lagrangian Floer homology for -actions

Erkao Bao, Tyler Lawson, Cheuk Yu Mak

For an odd prime , we prove a Smith inequality over for exact Lagrangian Floer homology under a symplectic -action, assuming an equivariant stable n…

From Morse Trees to -Holomorphic Discs -- Rigid Y-Graphs

Erkao Bao, Ke Zhu

The correspondence between Morse flow trees and -holomorphic discs was established by Fukaya--Oh and Ekholm. We revisit this correspondence and present an alternative approach,…

Equivariant Morse-Bott cohomology through stabilization

Erkao Bao, Robi Huq, Shengzhen Ning

For closed manifolds with compact Lie group actions, we study Austin-Braam's Morse-theoretic construction of Borel equivariant cohomology using the technique of stabilization. We s…

Computable, obstructed Morse homology for clean intersections

Erkao Bao, Ke Zhu

In this paper, we develop a method to compute the Morse homology of a manifold when descending manifolds and ascending manifolds intersect cleanly, but not necessarily transversely…

Coherent orientations in symplectic field theory revisited

Erkao Bao

In symplectic field theory (SFT), the moduli spaces of -holomorphic curves can be oriented coherently (compatible with gluing). In this note, we correct the signs involved in th…

Immersed Lagrangian Floer cohomology via pearly trajectories

Garrett Alston, Erkao Bao

We define Lagrangian Floer cohomology over -coefficients by counting pearly trajectories for graded, exact Lagrangian immersions that satisfy certain positivity condit…

Equivariant neural networks and equivarification

Erkao Bao, Jingcheng Lu, Linqi Song +3

Equivariant neural networks are a class of neural networks designed to preserve symmetries inherent in the data. In this paper, we introduce a general method for modifying a neural…

Equivariant Lagrangian Floer cohomology via semi-global Kuranishi structures

Erkao Bao, Ko Honda

Using a simplified version of Kuranishi perturbation theory that we call semi-global Kuranishi structures, we give a definition of the equivariant Lagrangian Floer cohomology of a…

Semi-global Kuranishi charts and the definition of contact homology

Erkao Bao, Ko Honda

We define the contact homology algebra for any contact manifold and show that it is an invariant of the contact manifold. More precisely, given a contact manifold and some…

Definition of Cylindrical Contact Homology in dimension three

Erkao Bao, Ko Honda

In this paper we give a rigorous definition of cylindrical contact homology for contact -manifolds that admit nondegenerate contact forms with no contractible Reeb orbits, and s…

Exact, graded, immersed Lagrangians and Floer theory

Garrett Alston, Erkao Bao

We develop Lagrangian Floer Theory for exact, graded, immersed Lagrangians with clean self-intersection using Seidel's setup. A positivity assumption on the index of the self inter…

On Hofer Energy of J-holomorphic Curves for Asymptotically Cylindrical J

Erkao Bao

In this paper, we provide a bound for the generalized Hofer energy of punctured -holomorphic curves in almost complex manifolds with asymptotically cylindrical ends. As an appli…

Holomorphic curves at one point

Erkao Bao

Let M be a closed symplectic manifold with a compatible almost complex structure J. We prove that for a point p in M and E>0, if v is a non-constant J-holomorphic curve with symple…

On J-holomorphic curves in almost complex manifolds with asymptotically cylindrical ends

Erkao Bao

Symplectic Field Theory studies J-holomorphic curves in almost complex manifolds with cylindrical ends. One natural generalization is to replace 'cylindrical' by 'asymptotically cy…
