具有梯度项的半线性degenerate parabolic equation的分层零能控性

Hierarchical null controllability of a semilinear degenerate parabolic equation with a gradient term

摘要:

本文将分层策略应用于一类带梯度项的半线性弱退化抛物方程。我们使用Stackelberg-Nash策略,其中一个领导者试图将解决方案驱动到零,两个追随者旨在解决双目标最优控制问题对应的纳什均衡。由于系统是半线性的,泛函一般不是凸的。为了克服这个困难,我们首先证明了纳什拟均衡的存在性和唯一性,这是一个较弱的制定的纳什均衡。其次,在附加条件下,我们建立了纳什拟均衡与纳什均衡的等价性。对伴随系统建立了一个适当的Carleman不等式,然后建立了一个能观性不等式。基于这个能观性不等式,我们证明了线性化系统的零能控性。然后,利用角谷不动点定理,得到了主系统的零能控性。

英文摘要:

In this paper, we apply the hierarchical strategy to a semilinear weakly degenerate parabolic equation involving a gradient term. We use the Stackelberg-Nash strategy with one leader which tries to drive the solution to zero and two followers intended to solve a Nash equilibrium corresponding to a bi-objective optimal control problem. Since the system is semilinear, the functionals are not convex in general. To overcome this difficulty, we first prove the existence and uniqueness of the Nash quasi-equilibrium, which is a weaker formulation of the Nash equilibrium. Next, with additional conditions, we establish the equivalence between the Nash quasi-equilibrium and the Nash equilibrium. We establish a suitable Carleman inequality for the adjoint system and then an observability inequality. Based on this observability inequality, we prove the null controllability of the linearized system. Then, due to the Kakutani's fixed point Theorem, we obtain the null controllability of the main system.
