Newton-Cartan connection is lifted to the degenerate spinor bundle over a Newton-Cartan 4-manifold by the aid of degenerate spin group. Levy-Leblond equation is constructed with the lifted connection.PhysicsL´evy-Leblond equations / FizikL´evy-Leblond denklemi EquationJournal Article1303-612242023990000611899
