$E_1$-degeneration and $d'd''$-lemma (1506.06451v2)

Abstract: For a double complex $(A, d', d'')$, we show that if it satisfies the $d'd''$-lemma and the spectral sequence ${E^{p, q}_r}$ induced by $A$ does not degenerate at $E_0$, then it degenerates at $E_1$. We apply this result to prove the degeneration at $E_1$ of a Hodge-de Rham spectral sequence on compact bi-generalized Hermitian manifolds that satisfy a version of $d'd''$-lemma.
