Abstract:

Let w be a Muckenhoupt weight and a Reifenberg flat domain in. Assume that and is a variable exponent satisfying the log-Hölder continuous condition. In this talk, we investigate the weighted variable Lorentz   regularity of the weak solutions of second order degenerate elliptic equations in divergence form with Dirichlet boundary condition, under the assumption that the degenerate coefficients belong to weighted BMO spaces with small norms.
