Gradient regularity for viscosity solutions to quasilinear parabolic equations with mixed singular-degenerate structure
Junior da Silva Bessa, João Vitor da Silva, Ginaldo de Santana Sá
We establish regularity results for viscosity solutions to a class of quasilinear parabolic equations exhibiting nonhomogeneous degeneracy or singularity (a double phase regime) of…
Comparison Principle, A.B.P.-type estimates for solutions of quasi-linear elliptic equations in non-divergence form and some implications
Junior da S. Bessa, Reshmi Biswas, João Vitor da Silva +2
In this work, we establish global gradient estimates to solutions of quasilinear elliptic models in non-divergence form with general degeneracy law and a Hamiltonian term, given by…
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…
Geometric regularity estimates for quasi-linear elliptic models in non-divergence form with strong absorption
Claudemir Alcantara, João Vitor da Silva, Ginaldo Sá
In this manuscript, we investigate geometric regularity estimates for problems governed by quasi-linear elliptic models in non-divergence form, which may exhibit either degenerate…
Regularity estimates to quasi-linear parabolic equations in non-divergence form with non-homogeneous signature
Junior da Silva Bessa, João Vitor da Silva, Ginaldo de Santana Sá
In this manuscript, we establish the existence and sharp geometric regularity estimates for bounded solutions of a class of quasilinear parabolic equations in non-divergence form w…
