Abstract: This article deals with the boundary null controllability of some degenerate parabolic equations posed on a square domain, presenting the first study of boundary controllability for such equations in multidimensional settings. The proof combines two classical techniques: the method of moments and the Lebeau-Robbiano strategy. A key novelty of this work lies in the analysis of boundary control localized on a subset of the boundary where degeneracy occurs. Furthermore, we establish a Kalman rank condition as a full characterization of boundary controllability for coupled degenerate systems. The results are extended to $ N $-dimensional domains, and some other potential extensions, along with open problems, are discussed to motivate further research in this area.
