A natural constraint for a quasilinear Schrodinger equation

In this paper, we obtain a natural constraint for a quasilinear Schrodinger equation involving a sign-changing weight function. We also prove that the energy functional is bounded from below on this constraint and its local minimizers are weak solutions of the equation
