SOLUTIONS FOR A NONHOMOGENEOUS p&q-LAPLACIAN PROBLEM VIA VARIATIONAL METHODS AND SUB-SUPERSOLUTION TECHNIQUE.

In this paper it is obtained, through variational methods and sub-supersolution arguments, existence and multiplicity of solutions for a nonhomogeneous problem which arise in several branches of science such as chemical reactions, biophysics and plasma physics. Under a general hypothesis it is proved an existence result and multiple solutions are obtained by considering an additional natural condition. [ABSTRACT FROM AUTHOR]
