Sommario:
- This paper addresses the controllability of a class of quasi-linear parabolic equations governed by multiplicative controls with mobile support. To prove the existence of such a control forcing the solution to rest at time $T>0$, we first establish the decay property of solutions for the uncontrolled system. Unlike the case of the linear heat equation, the nonlinearity in the principal part of the operator introduces significant challenges. These difficulties necessitate a novel approach, ultimately leading us to solve the controllability problem within the framework of classical solutions. Through a carefully constructed smooth transition, we demonstrate that there exists a multiplicative control driving the state exactly to rest at time $t=T$.
