Entire elliptic Hankel convolution equations

M. Belhadj, J. J. Betancor (2003)

Bollettino dell'Unione Matematica Italiana

In this paper we characterize the entire elliptic Hankel convolutors on tempered distributions in terms of the growth of their Hankel transforms.

Entrelacement de co-Poisson

Jean-François Burnol (2007)

Annales de l’institut Fourier

On connaît le lien intime qui existe entre les équations fonctionnelles des fonctions L et les formules sommatoires dont le prototype est donné par celle de Poisson. Ce lien fait intervenir la transformation intégrale de Fourier et ses généralisations. Ici, nous réexaminons la signification harmonique (ainsi qu’hilbertienne et distributionnelle) des équations fonctionnelles ayant la forme la plus simple, à savoir, celle s’appliquant pour la fonction dzêta de Riemann et les séries L de Dirichlet...

Equality of two diffeomorphism invariant Colombeau algebras

Jiří Jelínek (2004)

Commentationes Mathematicae Universitatis Carolinae

The two diffeomorphism invariant algebras introduced in Grosser M., Farkas E., Kunziger M., Steinbauer R., On the foundations of nonlinear generalized functions I, II, Mem. Amer. Math. Soc. 153 (2001), no. 729, 93 pp., are identical.

Equations in differentials in the algebra of generalized stochastic processes

Nadzeya V. Bedziuk, Aleh L. Yablonski (2010)

Banach Center Publications

We consider an ordinary or stochastic nonlinear equation with generalized coefficients as an equation in differentials in the algebra of new generalized functions in the sense of [8]. Consequently, the solution of such an equation is a new generalized function. We formulate conditions under which the solution of a given equation in the algebra of new generalized functions is associated with an ordinary function or process. Moreover the class of all possible associated functions and processes is...

Extension and lacunas of solutions of linear partial differential equations

Uwe Franken, Reinhold Meise (1996)

Annales de l'institut Fourier

Let K Q be compact, convex sets in n with K and let P ( D ) be a linear, constant coefficient PDO. It is characterized in various ways when each zero solution of P ( D ) in the space ( K ) of all C -functions on K extends to a zero solution in ( Q ) resp. in ( n ) . The most relevant characterizations are in terms of Phragmén-Lindelöf conditions on the zero variety of P in n and in terms of fundamental solutions for P ( D ) with lacunas.
