讨论形如du/dt=-Anu(t)+F(t,u(t)),u0=φ的非齐抛物型发展方程解的适定性与其非齐次项的关系,其中n阶广义微分算子-An为强连续半群的无穷小母元.作为应用,我们就二阶情形讨论一类具体的抛物型方程.

In this paper, we study the optimal control problem of nonlinear differentialinclusions with principle operator being pseudomonotone. First, we give some propertiesof solutions of certain evolution equations. Further, we prove the existence of admissibletrajectories for evolution inclusions. Then, we extend the Fillipov's selection theoremand discuss a general Lagrange type optimal control problem. Finally, we present anexample that demonstrates the appplicability of our results. 展开更多
