摘要
本文中我们讨论了Banach空间中带非局部初值条件u(0)=g(u)+u_0的半线性微分方程u′(t)=Au(t)+Bu(t)+f(t,u(t))的可控性问题,我们在g失去紧性条件时,给出了局部可控的充分条件.
In this paper,sufficient conditions are established for the nonlocally con- trollability of semilinear Cauehy problems u'(t)=Au(t)+ Bx(t)+f(t,u(t)),t∈I a.e., with nonlocal initial condition u(0)=g(u)+u_0 when the map g losing compactness.
