ABSTRACT We study two generalizations of the Holomorphic Morse Inequalities proved by Jean-Pierre Demailly in 1985: the case where the curvature of the line bundle is degenerate (maximum rank different from the dimension of the variety) and the case where the manifold is not compact. For these two cases, we prove precise theorems similar to the original one of [De 1]. The second part of the thesis investigates on one hand the study of an equivalent for the distortion function of a positive line bundle over a projective manifold; on the other hand we study the coeffective cohomology of a symplectic manifold. The main tools employed are those of differential geometry: Weyl asymptotic formula-type theorems, an equivalent for the heat kernel associated to Δ ′′ , and estimates on the curvature tensor.
