摘要

In this paper, a general class of semilinear evolution equations with impulses at variable times on infinite-dimensional Banach spaces is considered. Based on a discussion of the relationship between a curve Gamma(y) on [0, +infinity) x X and the semiflow W generated by the semilinear evolution system on [0, +infinity) x X and analysis about all case of impulses, we introduce a reasonable PC-mild solution of semilinear evolution equations with impulses at variable times and prove the local and global existence of the PC-mild solution and study the maximal existence interval of the solution.
