本文研究了非自治发展方程u(t)+A(t)u(t)=f(t),u(0)=0的极大正则性.如果在Hilbert空间H上考虑该方程,并且算子A(t)由半双线性形式a(t,n,n)定义,我们证明了在t→a(t,n,n)的Hölder连续性假设下的极大正则性。在非希尔伯特空间的情形下,我们主要研究薛定谔型算子A(t):=−Δ+m(t,n),并证明了一类广泛的依赖于时间和空间的势函数m的Lp− Lq估计。
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 a(t,⋅,⋅) we prove the maximal regularity under a Hölder continuity assumption of t→a(t,⋅,⋅). In the non-Hilbert space situation we focus on Schrödinger type operators A(t):=−Δ+m(t,⋅) and prove Lp−Lqestimates for a wide class of time and space dependent potentials m.
