摘要
该文在Lebesgue-Bochner空间L^p(T,X)和周期Besov空间B_(p,q)~s(T,X)上研究二阶有限时滞退化微分方程:(Mu′)′(t)=Au(t)+Bu′(t)+Fu_t+f(t)(t∈T:=[0,2π]),u(0)=u(2π),(Mu′)(0)=(Mu′)(2π)的适定性.利用向量值函数空间上的算子值傅里叶乘子定理,文中给出上述方程具有适定性的充要条件.
In this paper, we study the well-posedness of the second order degenerate differential equation: [Mu']'(t) = Au(t) + Bu'(t) + Fur+ f(t) (t∈ T := [0, 27r]) with periodic boundary conditions u(0) = u(2π), (Mu')(0) = (Mu1)(2π), in Lebesgue-Bochner spaces L^P(T,X) and periodic Besov spaces Bp,q^s (T, X). Using operator-valued Fourier multipliers theorems in vector- valued function spaces, we give necessary and sufficient conditions for the well-posedness of above equation.
