Existence of three nontrivial solutions for semilinear elliptic equations on ℝ<Superscript><Emphasis Type="Italic">N</Emphasis></Superscript>

We establish the existence theorem of three nontrivial solutions for a class of semilinear elliptic equation on ℝ ^N by using variational theorems of mixed type due to Marino and Saccon and linking theorem.  

Fractional <Emphasis Type="Italic">p</Emphasis>-Laplacian Equations with Subcritical and Critical Exponential Growth Without the Ambrosetti–Rabinowitz Condition

The main purpose of this paper is to investigate the existence of nontrivial solutions to a class of quasilinear non-local problems which do not satisfy the Ambrosetti–Rabinowitz (AR) condition where the nonlinear terms are superlinear at 0 and of subcritical or critical exponential growth (subcritical polynomial growth) at \(\infty \). Some existence results for nontrivial solution are obtained using mountain pass theorem combined with the fractional Moser–Trudinger inequality.
