Overdetermined Singular Problems and Fractional Torsion
Daniel Baratta
We study a Serrin-type overdetermined problem for the fractional Laplacian in a bounded open set with an isolated non-removable interior singularity. For positive weak solutions of…

Second order regularity for solutions to anisotropic degenerate elliptic equations
Daniel Baratta, Luigi Muglia, Domenico Vuono
We consider solutions to degenerate anisotropic elliptic equations in order to study their regularity. In particular we establish second-order estimates and enclose regularity resu…

Third order estimates and the regularity of the stress field for solutions to -Laplace equations
Daniel Baratta, Berardino Sciunzi, Domenico Vuono
We consider solutions to when approaches the semilinear limiting case and we get third order estimates. As a consequence we d…
