Abstract

This paper discusses noncommutative-geometry wormholes in the con- text of a cosmological model due to Sung-Won Kim. An ansatz suggested by the Friedmann-Lemaitre-Robertson-Walker (FLRW) model leads to the assump- tion that the matter content can be divided into two parts, a cosmological part depending only on time and a wormhole part depending only on space. These assumptions are sufficient for deriving a complete zero-tidal force wormhole solu- tion. The wormhole is evolving due to the scale factor in the FLRW model; it is restricted, however, to the curvature parameters k = 0 and k = −1. Unlike previ- ous models, the noncommutative-geometry background affects both the wormhole part and the cosmological part of the solution.
