【Abstract】 the exact controllability of a system described By semilinear heat equation yt=△y- f(x, t,y,y)+h(x,t), is studied by introducing an auxiliary system u′+△u=0, as well as the surjectivity of strong monotone operator. We give an exacT controllability under assumption (h) in finite time.更多还原
