    "abstract": "A new quantum deformation, which we call null-plane, of the (3+1) Poincar\\\u0027e\nalgebra is obtained. The algebraic properties of the classical null-plane\ndescription are generalized to this quantum deformation. In particular, the\nclassical isotopy subalgebra of the null-plane is deformed into a Hopf\nsubalgebra, and deformed spin operators having classical commutation rules can\nbe defined. Quantum Hamiltonian, mass and position operators are studied, and\nthe null-plane evolution is expressed in terms of a deformed Schr\\\"odinger\nequation.",
