This paper deals with existence, uniqueness and regularity of positive generalized solutions of singular nonlinear equations of the form in where are given, not necessarily continuous functions, and is a positive number. We explore both situations where are radial functions, with being eventually identically zero, and cases where no symmetry is required from either or . Schauder's fixed point theorem, combined with penalty arguments, is exploited.
