Query: Regularity results for nonlocal parabolic equations   We survey recent regularity results for parabolic equations involving
nonlocal operators like the fractional Laplacian. We extend the results of
Felsinger-Kassmann (2013) and obtain regularity estimates for nonlocal
operators with kernels not being absolutely continuous with respect to the
Lebesgue measure.
