三维时空中质量重力的“最小质量重力”模型(它具有与“拓扑质量重力”相同的反德西特(ADS)体积属性，但边界属性得到了改进)与物质相耦合。一致性需要一个特定的物质源张量，该张量在应力张量中是二次的。在渐近德西特(DS)宇宙学解的背景下，研究了理想流体从收缩到膨胀平滑反弹的结果。还发现了各种真空解决方案，包括翘曲的(A)DS和(对于参数的特定值)静态黑洞和A(A)DS
The'minimal massive gravity'model of massive gravity in three spacetime dimensions (which has the same anti-de Sitter (AdS) bulk properties as' topologically massive gravity'but improved boundary properties) is coupled to matter. Consistency requires a particular matter source tensor, which is quadratic in the stress tensor. The consequences are explored for an ideal fluid in the context of asymptotically de Sitter (dS) cosmological solutions, which bounce smoothly from contraction to expansion. Various vacuum solutions are also found, including warped (A) dS, and (for special values of parameters) static black holes and an (A) dS
