Gradient Regularity for Fully Nonlinear Equations with Variable Degeneracy and Hamiltonian Lower-Order Terms
Gleiciano Cosmo, Rafael R. Costa, Diego Marcon
We study local regularity properties of viscosity solutions to fully nonlinear elliptic equations with variable gradient degeneracy and Hamiltonian-type lower-order terms, \[ |\nab…

Regularity estimates for fully nonlinear dead-core problems with a Hamiltonian Term
Rafael R. Costa, Ginaldo S. Sá
In this paper, we present a problem involving fully nonlinear elliptic operators with Hamiltonian, which can present a singularity or degenerate as the gradient approaches the orig…
