Abstract: We study a parabolic system of the form

$\partial_tu=\operatorname{div}_xA(x,t,\nabla_xu)$ in a bounded cylinder

$Q_T=\Omega\times(0,T)\subset\mathbb R^{n+1}_{x,t}$ . Here the matrix function

$A(x,t,\xi)$ is subject to the conditions of power growth in the variable

$\xi$ and coercitivity with variable exponent

$p(x,t)$ . It is assumed that

$p(x,t)$ has a logarithmic modulus of continuity and satisfies the estimate

$\frac{2n}{n+2}<\alpha\le p(x,t)\le\beta<\infty.$
For the weak solution of the system, estimates of the higher integrability of the gradient are obtained inside the cylinder

$Q_T$ . The method of a solution is based on a localization of a special kind and a local variant (adapted for parabolic problems) of Gehring's lemma with variable exponent of integrability proved in the paper.

Keywords: parabolic system of variable order of nonlinearity, higher integrability for parabolic systems, Cacciopolli's inequality, Sobolev–Poincaré inequalities, Hölder's reverse inequality, Gehring's lemma, Lebesgue space, Sobolev–Orlicz space, Orlicz space.
