Minimal AdS-Lorentz supergravity in three-dimensions

Publication date: Available online 23 November 2018Source: Physics Letters BAuthor(s): O. Fierro, F. Izaurieta, P. Salgado, O. ValdiviaAbstractThe N=1 AdS-Lorentz superalgebra is studied and its relationship to semigroup expansion developed. Using this mathematical tool, the invariant tensors and Casimir operators are found. In terms of these invariants, a three-dimensional Chern–Simons supergravity action with AdS-Lorentz symmetry is constructed. The Killing spinors for a BTZ black-hole like solution of the theory are discussed.
