An Lq (Lp)-regularity theory for parabolic equations with integro-differential operators having low intensity kernels
In this article, we present the existence, uniqueness, and regularity of solutions to parabolic
equations with non-local operators∂ tu (t, x)= L au (t, x)+ f (t, x), t> 0 in L q (L p) spaces. Our …
