Maximal regularity for non-autonomous Schrödinger type equations

In this paper we study the maximal regularity property for non-autonomous evolution equations ∂tu(t)+A(t)u(t)=f(t), u(0)=0. If the equation is considered on a Hilbert space H and the operators A(t) are defined by sesquilinear forms we prove the maximal regularity under a Hölder continuity assumption of . In the non-Hilbert space situation we focus on Schrödinger type operators A(t):=−Δ+m(t, ) and prove Lp−Lq estimates for a wide class of time and space dependent potentials m.
