Regularization of distributions.
The differential -algebra of generalized functions of J.-F. Colombeau contains the space of Schwartz distributions as a -vector subspace and has a notion of ‘association’ that is a faithful generalization of the weak equality in . This is particularly useful for evaluation of certain products of distributions, as they are embedded in , in terms of distributions again. In this paper we propose some results of that kind for the products of the widely used distributions and , with in ,...
Models of singularities given by discontinuous functions or distributions by means of generalized functions of Colombeau have proved useful in many problems posed by physical phenomena. In this paper, we introduce in a systematic way generalized functions that model singularities given by distributions with singular point support. Furthermore, we evaluate various products of such generalized models when the results admit associated distributions. The obtained results follow the idea of a well-known...
