Positive solutions for the degenerate logistic indefinite superlinear problem the slow diffusion case
(University of Houston, 2003)
In this work we study the existence, stability and multiplicity of the positive steady-states solutions of the degenerate logistic indefinite superlinear problem. By an adequate change of variable, the problem is transformed ...
