We study the integral representation of solutions to the Cauchy problem for a differential equation with constant coefficients. The Cauchy data and the right-hand of the equation are given by entire functions on a complex hyperplane of . The Borel transformation of power series and residue theory are used as the main methods of investigation.
We show an explicit relation between the Chow form and the Grothendieck residue; and we clarify the role that the residue can play in the intersection theory besides its role in the division problem.
Our objective is to construct residue currents from Bochner-Martinelli type kernels; the computations hold in the non complete intersection case and provide a new and more direct approach of the residue of Coleff-Herrera in the complete intersection case; computations involve crucial relations with toroidal varieties and multivariate integrals of the Mellin-Barnes type.
Let be an open neighborhood of the origin in and let be complex analytic. Let be a generic linear form on . If the relative polar curve at the origin is irreducible and the intersection number is prime, then there are severe restrictions on the possible degree cohomology of the Milnor fiber at the origin. We also obtain some interesting, weaker, results when is not prime.
We find a relation between the vanishing of a globally defined residue current on and solution of the membership problem with control of the polynomial degrees. Several classical results appear as special cases, such as Max Nöther’s theorem, for which we also obtain a generalization. Furthermore there are some connections to effective versions of the Nullstellensatz. We also provide explicit integral representations of the solutions.
On utilise le calcul résiduel pour un calcul effectif de la trace d’une forme méromorphe sur une hypersurface analytique permettant d’obtenir une caractérisation des formes traces. En conséquence, une version plus forte du théorème d’Abel-inverse global que celle donnée dans [16] est prouvée : le courant est algébrique si et seulement si sa transformée d’Abel est rationnelle en les variables ne correspondant pas à la pente. La preuve s’appuie sur des mécanismes algébriques d’inversion et sur...
