This article studies of null controllability property of nonlinear coupled one dimensional degenerate parabolic equations. These equations form a cascade system. that is. the solution of the first equation acts as a control in the second equation and the control function acts only directly on the first equation. https://www.bekindtopets.com/super-grab-Wizarding-World-Hogwarts-Legacy-Main-Poster-iPhone-14-Plus-Clear-Case-p36756-quick-choice/
