Positive solutions for critical singular elliptic equations without Ambrosetti-Rabinowitz type conditions

Communications in Analysis and Mechanics
We study the subcritical approximations to Li–Lin's open problem, proposed by Li and Lin (Arch Ration Mech Anal 203(3): 943-968, 2012). By applying the variational method, we obtain two positive solutions. We establish a nonexistence theorem for positive

Existence of three positive solutions for a p-sublinear problem involving a Schrodinger p-Laplacian type operator

Electronic Journal of Differential Equations
We prove the existence of three positive solutions for the problem $$\disolaylines{ -\Delta_p u + V (x)\varphi_p(u)=\lambda f(u),\quad x\in \Omega, \cr u(x)=0, \quad x\in \partial\Omega, } $$ where $\lambda >0$, $\Delta_p$ is the $p$-Laplacian ...

Unbounded Supersolutions of Nonlinear Equations with Nonstandard Growth

Boundary Value Problems, 2007
We show that every weak supersolution of a variable exponent -Laplace equation is lower semicontinuous and that the singular set of such a function is of zero capacity if the exponent is logarithmically Hölder continuous.
