Abstract

In this paper we investigate the improved Caccioppoli inequality and the reverse H\"{o}lder inequality for gradients of weak solutions to nonhomogeneous parabolic systems whose coefficients can be split into a complex-valued and bounded part, which also satisfies the uniform Ga˚\mathring{a}rding inequality, and a real and anti-symmetric part in BMO. In particular, unbounded coefficients are allowed.
