In this paper,the author considers an elliptic problem with critical and sublinear growth.Some results about the multiplicity and uniqueness of the positive solutions are given by making use of variational method and ...
This paper mainly studies the existence of positive solutions of singular sub-linear boundary value problems concerning the generalized Emden-Fowler equations. Anecessary and sufficient condition for the existence of ...
In this paper,we prove the existence of multiple periodic solutionsfor a class of singular Hamiltonian systems with sublinear terms via variationalmethods.
