New Positive Solutions of Nonlinear Elliptic PDEs
New Positive Solutions of Nonlinear Elliptic PDEs
We are concerned with positive solutions of two types of nonlinear elliptic boundary value problems (BVPs). We present conditions for existence, uniqueness and multiple positive solutions of a first type of elliptic BVPs. For a second type of elliptic BVPs, we obtain conditions for existence and uniqueness of positive global …
