Harnack-type estimates for nonlocal double phase functionals

Yuzhou Fang, Chao Zhang

We establish Harnack-type inequalities for local minimizers of nonlocal double phase functionals, involving an explicit two-radius positive-part tail and a negative far-field tail.…

Gradient regularity for nonlocal double phase equations

Yuzhou Fang, Chao Zhang

This paper is devoted to investigating the interior regularity of viscosity solutions to the nonlocal double phase equations $$ \int_{\mathbb{R}^d} \left(\frac{|u(x)-u(y…

Regularity theory for degenerate fully nonlinear nonlocal equations with a Hamiltonian term

Yuzhou Fang, Juha Kinnunen, Chao Zhang

We investigate a class of degenerate fully nonlinear nonlocal elliptic equations with Hamiltonian terms. By precisely characterizing the interaction between the degeneracy law of e…

Higher Sobolev regularity for mixed local and nonlocal equations with nonstandard growth

Yuzhou Fang, Dingding Li, Chao Zhang

We develop a systematic study of the interior Sobolev regularity of weak solutions to the mixed local and nonlocal -Laplace equations, which model the superposition of two s…

Regularity for a class of degenerate fully nonlinear nonlocal elliptic equations

Yuzhou Fang, Vicentiu D. Radulescu, Chao Zhang

We consider a wide class of fully nonlinear integro-differential equations that degenerate when the gradient of the solution vanishes. By using compactness and perturbation argumen…

Quantitative analysis and its applications for Keller-Segel type systems

Mengyao Ding, Yuzhou Fang, Chao Zhang

In this paper, we utilize the De Giorgi iteration to quantitatively analyze the upper bound of solutions for Keller-Segel type systems. The refined upper bound estimate presented h…
