Linear non-autonomous Cauchy problems and evolution semigroups
نویسندگان
چکیده
The paper is devoted to the problem of existence of propagators for an abstract linear non-autonomous evolution Cauchy problem of hyperbolic type in separable Banach spaces. The problem is solved using the so-called evolution semigroup approach which reduces the existence problem for propagators to a perturbation problem of semigroup generators. The results are specified to abstract linear non-autonomous evolution equations in Hilbert spaces where the assumption is made that the domains of the quadratic forms associated with the generators are independent of time. Finally, these results are applied to time-dependent Schrödinger operators with moving point interactions in 1D. AMS-subject classification: Primary 35L90; Secondary 34G10, 47D06

Evolution Semigroups for Nonautonomous Cauchy Problems
In this paper, we characterize wellposedness of nonautonomous, linear Cauchy problems (NCP ) { u̇(t) = A(t)u(t) u(s) = x ∈ X on a Banach space X by the existence of certain evolution semigroups. Then, we use these generation results for evolution semigroups to derive wellposedness for nonautonomous Cauchy problems under some “concrete” conditions. As a typical example, we discuss the so called “...
متن کاملON INTEGRATED SEMIGROUPS AND AGE STRUCTURED MODELS IN Lp SPACES
In this paper, we first develop some techniques and results for integrated semigroups when the generator is not a Hille-Yosida operator and is non-densely defined. Then we establish a theorem of Da Prato and Sinestrari’s type for the nonhomogeneous Cauchy problem and prove a perturbation theorem. In particular, we obtain necessary and sufficient conditions for the existence of mild solutions fo...
متن کاملTime-dependent delta-interactions for 1D Schrödinger Hamiltonians
The non autonomous Cauchy problem i∂tu = −∂ 2 xxu+α(t)δ0u with ut=0 = u0 is considered in L(R) . The regularity assumptions for α are accurately analyzed and show that the general results for non autonomous linear evolution equations in Banach spaces are far from being optimal. In the mean time, this article shows an unexpected application of paraproduct techniques, initiated by J.M. Bony for n...
متن کاملPerturbations of Bi-continuous Semigroups
initial value problems (Cauchy problems) are usually studied via operator semigroups. In many cases, the well-developed theory of C0-semigroups, i.e., one-parameter operator semigroups which are strongly continuous for the norm on a Banach space X , suffices and provides a powerful machinery to study such problems. The applications range from partial differential equations, Volterra integro-dif...
متن کاملNon-autonomous Integrodifferential Equations with Non-local Conditions
Recent results concerning the existence and uniqueness of mild and classical solutions for non-local Cauchy problems are extended to the following non-autonomous semilinear integrodifferential equation u′(t) = A(t) [ u(t) + ∫ t 0 F (t, s)u(s) ds ] + f(t, u(t)), 0 ≤ t ≤ T, u(0) + g(t1, . . . , tp, u(t1), . . . , u(tp)) = u0, in a Banach space X, with A(·) the generators of strongly continuous se...
