Abstract

We show that infinite families of non-relativistic spin- symmetries in dimensions, which include higher-spin extensions of the Bargmann, Newton-Hooke, non-relativistic Maxwell, and non-relativistic AdS-Lorentz algebras, can be obtained as Lie algebra expansions of two different spin- extensions of the Nappi-Witten symmetry. These higher-spin Nappi-Witten algebras, in turn, are obtained by means of Inönü-Wigner contractions applied to suitable direct product extensions of . Conversely, we show that the same result can be obtained by considering contractions of expanded algebras. The method can be used to define non-relativistic higher-spin Chern-Simon gravity theories in dimensions in a systematic way.
