Infinitely Many Solutions for a Semilinear Elliptic Equation with Sign-Changing Potential
We consider a similinear elliptic equation with sign-changing potential −Δu−V(x)u=f(x,u), u∈H1(ℝN), where V(x) is a function possibly changing sign in ℝN. Under certain assumptions on f, we prove that the equation has infinitely many...
