摘　　要：一类脉冲偏泛函微分方程在无界区域上的吸引性被研究.首先利用基本解理论,建立了这类方程柔解的积分表达式.然后,使用非负矩阵性质和不等式分析技巧,给出判断吸引集和不变集的一些充分条件.The attraction for a nonlinear impulsive partial functional differential equation in a unbounded domain is investigated.By applying the method of fundamental solution,a variation of constants formula is established for the mild solution of the equation.By using the properties of nonnegative matrices and inequality techniques,some sufficient criteria for attracting set and invariant set are obtained.

关 键 词：吸引性 不变集 柔解 脉冲 偏泛函微分方程
