论文摘要
几乎研究了最低尺寸的几乎副键。这种结构分别是在4维空间（欧几里得和伪欧国人）中的超球体上构建的。根据所使用的分类及其几何特性，研究了所获得的歧管和表征。
Almost paracontact almost paracomplex Riemannian manifolds of the lowest dimension are studied. Such structures are constructed on hyperspheres in 4-dimensional spaces, Euclidean and pseudo-Euclidean, respectively. The obtained manifolds are studied and characterised in terms of the classification used and their geometric properties.
