A -caloric approximation and partial regularity for parabolic systems with Orlicz growth

We prove a new A-caloric approximation lemma compatible with an Orlicz setting. With this result, we establish a partial regularity result for parabolic systems of the type ut-diva(Du)=0.Here the growth of a is bounded by the derivative of an N-function φ. The primary assumption for φ is that tφ′ ′(t) and φ′(t) are uniformly comparable on (0 , ∞)
