Abstract:

In this paper, a class of semilinear elliptic equations with sublinear and superlinear nonlinearities in RN is studied. By making use of variational method and L1 estimation, the authors obtain some results about existence of multiple positive solutions and asymptotic behavior of the solutions.

Key words: Concave, convex, critical point, asymptotic behavior
