Infinitely many solutions for critical fractional equation with sign-changing weight function
Wei Chen,Chunlei Tang
Keywords:Fractional Schrodinger equations, critical exponent, sign-changing weight function, symmetric Mountain Pass Theorem.
      In this work, we consider the fractional Schrodinger type equations with critical exponent, concave nonlinearity and sign-changing weight function on $\mathbb{R}^N$. With the aid of the symmetric Mountain Pass Theorem, we prove this problem has infinitely many small energy solutions.
