A closed set K of a Hilbert space H is said to be invariant under the evolution equation
X ( t ) = A X ( t ) + f t , X ( t ) ( t > 0 ) ,
whenever all solutions starting from a point of K , at any time t 0 0 , remain in K as long as they exist.

Hilbert空间中半线性发展方程局部解的区域不变性

封闭集 ķ 希尔伯特空间 H 据说在演化方程下是不变的
X Ť = 一种 X Ť + F Ť X Ť Ť > 0
只要所有解决方案都从 ķ ,随时 Ť 0 0 , 留在 ķ 只要它们存在。
