Description
We present our recent work that is the description of a gravitational theory as a gague theory on a covariant noncommutative space. First, we remind the most basics of the translation of gravity theories to the gauge theory language and also the tools we use to construct gauge theories on noncommutative spaces. Then, we describe the construction of the covariant noncommutative space, that is a fuzzy version of the four-dimensional de Sitter space. In turn, we move on with the construction of a four-dimensional gravity model in a gauge-theoretic way, with the group to be gauged to be identified as a subgroup of the isometry group of the above space. Last, we present our results and comment on the commutative limit.
