摘要:
本文利用~$C_0$ 半群和~Banach 压缩映射原理研究了~Banach 空间脉冲积分 - 微分发展方程适度解的存在性、唯一性和解对初值的连续依赖性,并给出了适度解的具体迭代逼近序列和误差估计. 本文的条件更弱更具一般性,所得结果推广和改进了一些已知的结果.

Abstract:
The existence, uniqueness and continuous dependence of a mildsolution for the nonlinear impulsive integro-differential evolutionequations in Banach spaces are studied. Methods of a $C_0$ semigroupof operators and the Banach contraction theorem are applied. Inaddition, an explicit iterative approximation of the mild solutionand an error estimate of the approximation sequence are derived. Theassumed conditions in the present theorems are weaker and moregeneral, and the results obtained generalize and improve someknown results.
