Correction to the paper "A flexible construction of equivariant Floer homology and applications"

TL;DR

This paper corrects a mistake in a previous work on equivariant Floer homology, providing an alternative proof for the invariance of equivariant symplectic Khovanov homology, without affecting the main results.

Contribution

It offers a correction and an alternative proof for the invariance of equivariant symplectic Khovanov homology in a prior publication.

Findings

The main results remain valid despite the correction.

An alternate proof of invariance is provided.

The correction clarifies the role of almost complex structures.

Abstract

We correct a mistake regarding almost complex structures on Hilbert schemes of points in surfaces in arXiv:1510.02449. The error does not affect the main results of the paper, and only affects the proofs of invariance of equivariant symplectic Khovanov homology and reduced symplectic Khovanov homology. We give an alternate proof of the invariance of equivariant symplectic Khovanov homology.
