Sufficient conditions for the existence of positive solutions to a class of quasilinear elliptic equations in two-dimensional exterior domains are given.
In this paper, we generalize the fixed point theorem of cone expansion and compression of norm type to the theorem of functional type. As an application, the existence of positive solutions for some f...
This paper presents a lower and upper solution technique for singular second order boundary value problems on the half line.
This paper mainly studies the existence of positive solutions of singular sub-linear boundary value problems concerning the generalized Emden-Fowler equations. A necessary and sufficient condition for...
This paper studies the existence of solutions of the following problem: where Ω is a bounded domain in Rn with smooth boundary, L is a second order uniformly elliptic linear operator, and f(x, u ε) is...
We study the existence of positive solutions of nonlinear degenerate elliptic equations with the aid of phase-energy method. The equivalent conditions are given for the existence of positive solutions...
