Global regularity for a class of degenerate/singular fully nonlinear elliptic equations with Hamiltonian terms
Jiangwen Wang, Feida Jiang
In this paper we establish sharp global regularity for a class of degenerate/singular fully nonlinear elliptic equations featuring Hamiltonian structures. The results pr…
Boundary regularity for degenerate fully nonlinear elliptic equations on domain
Jiangwen Wang, Feida Jiang
In this article, we establish global regularity results (, and estimates) for a class of degenerate fully nonlinear equation on -domain. Th…
Improved regularity estimates for degenerate or singular fully nonlinear dead-core systems and Hénon-type equations
Jiangwen Wang, Feida Jiang
In this paper, we study the degenerate or singular fully nonlinear dead-core systems coupled with strong absorption terms. We establish several properties, including improved regul…
Far field refraction problem with loss of energy in negative refractive index material
Haokun Sui, Feida Jiang
This paper studies the far field refraction problem in negative refractive index material with loss of energy, which is a remaining problem in E. Stachura, Nonlinear Anal. 2017;157…
Regularity for fully nonlinear degenerate parabolic equations with strong absorption
João Vitor da Silva, João Vitor da Silva, Feida Jiang +1
In this paper, we investigate dead-core problems for fully nonlinear degenerate parabolic equations with strong absorption, \begin{equation*} |Du|^{p} F(D^{2}u) - u_{t} = λ_{0}(x,t…
Regularity of solutions for degenerate or singular fully nonlinear integro-differential equations
Jiangwen Wang, Feida Jiang
We study a series of regularity results for solutions to a degenerate or singular fully nonlinear integro-differential equation of the form $$- \big( Ï_{1}(|Du|) + a(x) Ï_{2}(|Du…
