Multiple solutions for a class of sublinear Schrödinger equations

Infinitely Many Solutions for a Class of Sublinear Schrödinger Equations

where V : R → R and f : R × R → R. In the past several decades, the existence and multiplicity of nontrivial solutions for problem (1.1) have been extensively investigated in the literature with the aid of critical point theory and variational methods. Many papers deal with the autonomous case where the potential V and the nonlinearity f are independent of x, or with the radially symmetric case...

A Priori Estimates of Positive Solutions for Sublinear Elliptic Equations

In this paper, a priori estimates of positive solutions for sublinear elliptic equations are given in terms of thicknesses of domains. To this end, a supersolution is constructed by a composite function of a solution to an ordinary differential equation and a distance function. The results work efficiently in the case where the domain is an exterior or an interior of a convex set.
