Abstract
A slight modification of the definition of the Colombeau generalized functions allows to have a canonical embedding of the space of the distributions into the space of the generalized functions on a C∞ manifold. The previous attempt in [5] is corrected, several equivalent definitions are presented.

The use of generalized functions and distributions in general relativity

TL;DR: In this paper, a mathematical theory of nonlinear generalized functions based on Colombeau algebras is described and applied in general relativity, and it is shown that certain solutions with weak singularities may be regarded as distributional solutions of Einstein's equations.

A Global Theory of Algebras of Generalized Functions

TL;DR: In this article, a geometric approach to define an algebra G (M) (the Colombeau algebra) of generalized functions on a smooth manifold M containing the space D ∞(M) of distributions on M. This algebra is a differential algebra, its elements possessing Lie derivatives with respect to arbitrary smooth vector fields.

The use of Generalised Functions and Distributions in General Relativity

TL;DR: In this article, the authors review the extent to which one can use classical distribution theory in describing solutions of Einstein's equations and show that there are some physically interesting cases which cannot be treated using distribution theory but require a more general concept.

Théorie des distributions

TL;DR: The merite as discussed by the authors is a date marque une date dans le progres des mathematiques and de la physique en levant l'ambiguite que constituait le succes des methodes de calcul symbolique aupres des physiciens and l'inacceptabilite de leurs formules au regard de la rigueur mathematiques.

Elementary introduction to new generalized functions

TL;DR: In this article, the author's previous book ''New Generalized Functions and Multiplication of Distributions' (North-Holland, 1984) introduced ''new generalized functions'' in order to explain heuristic computations of physics and to give a meaning to any finite product of distributions.
