Abstract
Let be a positively graded commutative Noetherian ring with onedimensional local base ring . Let be an primary ideal. Let be a finitely generated graded module and let . Let denote the th local cohomology module of with respect to the irrelevant ideal of . The main results in this paper are: "(a)" Assume that for all . Then there is a polynomial of degree such that for all , e_1(_0,H^i_(M)_n)=S(n), where is the socalled first HilbertSamuel coefficient of with respect to . "(b)" There is some such that for all , where is the postulation number of the module with respect to .
