Abstract
AbstractWe prove a new $$\mathcal {A}$$
A
-caloric approximation lemma compatible with an Orlicz setting. With this result, we establish a partial regularity result for parabolic systems of the type $$\begin{aligned} u_{t}- {{\,\textrm{div}\,}}a(Du)=0. \end{aligned}$$

Here the growth of a is bounded by the derivative of an N-function $${\varphi }$$
φ
. The primary assumption for $${\varphi }$$
