“…In particular, Betti numbers, Hodge numbers, Bott-Chern and Aeppli numbers are linear combinations of the multiplicities mult Z (A) for zigzags Z, see [S21, Corollary B]. We also recall that an E 1 -isomorphism is a morphism of bounded double complexes inducing an isomorphism on the first page of the Frölicher spectral sequence, see [S21,Definition D]. By [S21, Proposition E], the E 1 -isomorphism type of a bounded double complex is completely described by the multiplicities of all non-projective indecomposable bicomplexes (i.e.…”
