Gauge Theories on Fuzzy Spaces and Gravity (1911.04483v2)

Published 11 Nov 2019 in hep-th and gr-qc

Abstract: We start by briefly reviewing the description of gravity theories as gauge theories in four dimensions. More specifically we recall the procedure leading to the results of General Relativity and Weyl Gravity in a gauge-theoretic manner. Then, after a brief reminder of the formulation of gauge theories on noncommutative spaces, we review our recent work, where gravity is constructed as a gauge theory on the fuzzy $dS_4$.
