• 1-differentiable form
• coeffective cohomology
• almost contact structure

After a brief review of some basic notions concerning 1 differentiable cohomology, named here (d) over tilde -cohomology, we introduce a Lichnerowicz (d) over tilde -cohomology in a classical way. Next, following the classical study of coeffective cohomology, a special attention is paid to the study of some problems concerning coeffective cohomology in the graded algebra of 1-differentiable forms. Also, the case of an almost contact metric (2n+1)-dimensional manifold is considered and studied in our context.
