Construction of a Control for the Cubic Semilinear Heat Equation

 http://repository.vnu.edu.vn/handle/VNU_123/26706
In this article, we consider the null controllability problem for the cubic semilin-ear heat equation in bounded domains ofR n , n≥3 with Dirichlet boundary conditions for small initial data.

A constructive way to compute a control function acting on any nonempty open subsetωof is given such that the corresponding solution of the cubic semilinear heat equation can be driven to zero at a given final timeT.

Furthermore, we pro-vide a quantitative estimate for the smallness of the size of the initial data with respect toT that ensures the null controllability property.

Abstract:	In this article, we consider the null controllability problem for the cubic semilin-ear heat equation in bounded domains ofR n , n≥3 with Dirichlet boundary conditions for small initial data. A constructive way to compute a control function acting on any nonempty open subsetωof is given such that the corresponding solution of the cubic semilinear heat equation can be driven to zero at a given final timeT. Furthermore, we pro-vide a quantitative estimate for the smallness of the size of the initial data with respect toT that ensures the null controllability property.
