    "abstract": "The non-standard (Jordanian) quantum deformations of $so(2,2)$ and (2+1)\nPoincar\\\u0027e algebras are constructed by starting from a quantum $sl(2,\\R)$ basis\nsuch that simple factorized expressions for their corresponding universal\n$R$-matrices are obtained. As an application, the null-plane quantum (2+1)\nPoincar\\\u0027e Poisson-Lie group is quantized by following the FRT prescription.\nMatrix and differential representations of this null-plane deformation are\npresented, and the influence of the choice of the basis in the resultant\n$q$-Schr\\\"odinger equation governing the deformed null plane evolution is\ncommented.",
