Existence and multiplicity of positive solutions for singular p&q-Laplacian problems via sub-supersolution method

Suellen Cristina Q. Arruda, Rubia G. Nascimento

In this work we show the existence and multiplicity of positive solutions for a singular elliptic problem which the operator is non-linear and non-homogenous. We use the sub-supersolution method to study the following class of p&q-singular problems

where Ω is a bounded domain in RN with N≥3, 2≤p<N and γ>0. The hypotheses on the functions a, h, and f allow us to extend this result to a large class of problems.
