Analytic continuation of fundamental solutions to differential equations with constant coefficients

Christer O. Kiselman (2011)

Annales de la faculté des sciences de Toulouse Mathématiques

Similarity:

If P is a polynomial in R n such that 1 / P integrable, then the inverse Fourier transform of 1 / P is a fundamental solution E P to the differential operator P ( D ) . The purpose of the article is to study the dependence of this fundamental solution on the polynomial P . For n = 1 it is shown that E P can be analytically continued to a Riemann space over the set of all polynomials of the same degree as P . The singularities of this extension are studied.

Strong boundary values : independence of the defining function and spaces of test functions

Jean-Pierre Rosay, Edgar Lee Stout (2002)

Annali della Scuola Normale Superiore di Pisa - Classe di Scienze

Similarity:

The notion of “strong boundary values” was introduced by the authors in the local theory of hyperfunction boundary values (boundary values of functions with unrestricted growth, not necessarily solutions of a PDE). In this paper two points are clarified, at least in the global setting (compact boundaries): independence with respect to the defining function that defines the boundary, and the spaces of test functions to be used. The proofs rely crucially on simple results in spectral asymptotics. ...
