Nontrivial solutions for asymmetric problems on R^N

We consider the elliptic equation $$ -\Delta u+V(x)u= f(x,u), \quad x\in \mathbb{R}^n, \quad u\in H^1(\mathbb{R}^N),\; N\geq 2, $$ where $V(x)\in C(\mathbb{R}^N)$ and $V(x)\geq V_0>0$ for all $x\in \mathbb{R}^N$. The nonlinear term $f$ exhibits an asymmetric growth at $+\infty$ and $-\in...
