Wolff potentials and nonlocal equations of Lane-Emden type
Quoc-Hung Nguyen, Jihoon Ok, Kyeong Song
We consider nonlocal equations of the type \[ (-Î_{p})^{s}u = μ\quad \text{in}\;\; Ω, \] where is either a bounded domain or the whole $\mathbb{R}^{n}…

Regularity for mixed-order nonlinear fractional equations with degenerate coefficients
Ho-Sik Lee, Jihoon Ok, Kyeong Song
We consider a class of nonlinear integro-differential equations whose leading operator is obtained as a superposition of and , where $0<s<t<1<p<\inft…

Nonlocal equations with kernels of general order
Jihoon Ok, Kyeong Song
We consider a broad class of nonlinear integro-differential equations with a kernel whose differentiability order is described by a general function . This class includes not o…
