Classifications (with respect to both the Levi-Civita and the first canonical connections) of almost Golden Riemannian manifolds with null trace are obtained, expressing them in terms of the tensors defining the structure. Previously, classification (with respect to the first canonical connection) of almost product Riemannian manifolds with null trace is also obtained.

零痕迹的概金黎曼流形的分类

获得具有零迹的几乎黄金黎曼流形的分类（关于Levi-Civita和第一个规范连接），并用定义结构的张量表示。以前，还获得了具有零迹线的几乎乘积黎曼流形的分类（相对于第一个规范连接）。
