Correction to the article: A cylindrical reformulation of Heegaard Floer homology

##### Abstract

This note corrects a serious mistake in the computation of the embedded index in “A cylindrical reformulation of Heegaard Floer homology.” (The mistake is in a lemma about representing homology classes by surfaces.) It also corrects several smaller mistakes. The main results of the original paper are unchanged.
