Local-Nonlocal Schrödinger Equation with Critical Exponent: The Zero Mass Case

Abstract

In this paper, we consider the critical problem involving local and nonlocal operator with critical exponent under the zero mass case. First, we establish the continuous and compactness Sobolev embedding results. Second, we establish the non-existence result by Pohožaev identity. Finally, we prove the existence results for upper-crtical and lower-crtical cases via Sobolev embedding theorem, Mountain-pass theorem and Nehari manifold.
