Let X be a compact complex manifold, and let : X ! B be a small deformation of X, the dimensions of the Bott-Chern cohomology groups or Aeppli
cohomology groups may vary under this deformation. In [1], M. Schweitzer constructed a complex of sheaves Lp,q, and represented Bott-Chern cohomology groups or Aeppli cohomology groups as the cohomology groups of Lp,q. In [2], the author have studied this jumping phenomenon by studying the deformation obstructions of a hypercohomology class of a complex of sheaves B p,q which is quasi-isomorphic to L p,q[1]. In particular, they obtain an explicit formula for the obstructions. In this paper, the formula of the first order obstruction is proved in another way by using cohomology of L p,q.
