BIFURCATION OF SOLUTIONS FOR AN ELLIPTIC DEGENERATE PROBLEM
S. AMRAOUI, M. IGUERNANE
Abstract
We investigate the existence and bifurcation of solutions of a model nonlinear degenerate elliptic differential equation: in ; . This model is related to a simplified version of the nonlinear Wheeler-De Witt equation as it appears in quantum cosmological models, see [8, 9, 10].
