Solutions to some nonlinear PDE's in the form of Laplace type integrals

Maria E. Pliś (2002)

Annales Polonici Mathematici

A nonlinear equation P ( D ) u = α u m in 2 variables is considered. A formal solution as a series of Laplace integrals is constructed. It is shown that assuming some properties of Char P, one gets the Gevrey class of such solutions. In some cases convergence “at infinity” is proved.

The Fourier integral for a certain class of distributions

Josef Matušů (1991)

Applications of Mathematics

The aim of this paper is to derive by elementary means a theorem on the representation of certain distributions in the form of a Fourier integral. The approach chosen was found suitable especially for students of post-graduate courses at technical universities, where it is in some situations necessary to restrict a little the extent of the mathematical theory when concentrating on a technical problem.
