Existence of positive solutions for semilinear elliptic equations in annular domains
During recent years much work has been devoted to the study of positive solutions of semilinear elliptic equations where the nonlinear terms grow superlinearly at infinity.Many results exist which show that depending upon the topology of the underlying domain (see [1,5]), different existence results must be expected, and in fact, …
