An $L_{q} (L_{p})$ -regularity theory for parabolic equations with integro-differential operators having low intensity kernels

Jaehoon Kang, Daehan Park

In this article, we present the existence, uniqueness, and regularity of solutions to parabolic equations with non-local operators $$ \partial_{t}u(t,x) = \mathcal{L}^{a}u(t,x) + f…

A regularity theory for parabolic equations with anisotropic non-local operators in $L_{q} (L_{p})$ spaces

Jae-Hwan Choi, Jaehoon Kang, Daehan Park

In this paper, we present an $L_{q} (L_{p})$ -regularity theory for parabolic equations of the form: $\partial_{t} u (t, x) = L^{a, b} (t) u (t, x) + f (t, x), u (0, x) = 0.$ …

An $L_{q} (L_{p})$ -theory for time-fractional diffusion equations with nonlocal operators generated by Lévy processes with low intensity of small jumps

Jaehoon Kang, Daehan Park

We investigate an $L_{q} (L_{p})$ -regularity ( $1 < p, q < \infty$ ) theory for space-time nonlocal equations of the type $\partial_{t}^{α} u = L u + f$ . Here, $\partial_{t}^{α}$ is the…

An $L_{q} (L_{p})$ -theory for diffusion equations with space-time nonlocal operators

Kyeong-hun Kim, Daehan Park, Junhee Ryu

We present an $L_{q} (L_{p})$ -theory for the equation $\partial_{t}^{α} u = ϕ (Δ) u + f, t > 0, x \in R^{d}; u (0, \cdot) = u_{0} .$ Here $p, q > 1$ , $α \in (0, 1)$ , $\partial…
