We consider a non-autonomous evolutionary problem u′(t)+ A (t) u (t)= f (t), u (0)= u 0, where V, H are Hilbert spaces such that V is continuously and densely embedded in H and the operator A (t): V→ V′ is associated with a coercive, bounded, symmetric form a (t,.,.): V× V→ C for all t∈[0, T]. Given f∈ L 2 (0, T; H), u 0∈ V there exists always a unique solution u∈ MR (V, V′):= L 2 (0, T; V)∩ H 1 (0, T; V′). The purpose of this article is to investigate whether u∈ H 1 (0, T; H). This property of maximal regularity in H is not known in general. We give a positive answer if the form is of bounded variation; ie, if there exists a bounded and non-decreasing function g:[0, T]→ R such that| a (t, v, w)− a (s, v, w)|≤[g (t)− g (s)]‖ v‖ V‖ w‖ V (0≤ s≤ t≤ T, v, w∈ V). In that case, we also show that u (.) is continuous with values in V. Moreover we extend this result to certain perturbations of A (t).
