文摘

The purpose of this paper is to extend the bilinearity of the Segre product that has been proved recently by Ilse Fischer and Martina Kubitzke under some restricted hypotheses. As a consequence, we get some formulas involving Eulerian polynomials and a nice formula that will be used by the first author to solve the Simon Newcomb problem. We apply these results to compute the postulation number of a series and extend partially the results about Castelnuovo-Mumford regularity of the Segre product of polynomial rings of David A. Cox and Evgeny Materov.
