#### Akivis derivation formulas and Laptev structure equations on the surface of an **affine** **space**

The smooth surface in **affine** **space** is considered. With the derivation formulas and equations of the structure of an **affine** **space** constructed three pairs Akivis-Laptev on the surface. It is shown that the surface of an **affine** **space** is a holonomic smooth manifold.

#### About fields of geometrical objects of the H -distribution of the **affine** **space**

A creation of geometric objects of the hyperband distribution (H -distribution) of **affine** **space** An in the differential 1–3rd orders neighborhoods is continued. As a result a number of new normalization in Norden's sense of the main structural subbundles of this H -distribution are constructed (are found) internally invariantly.

#### A geometric model of a three-parametrical family of ellipsoids

A three-parametrical family of ellipsoids in three-dimensional **affine** **space** with special geometric properties is considered. A geometrical model of this manifold is constructed.

#### About fields of geometrical objects connected with the complex central nondegenerate hyperquadrics

A field of some geometrical objects internally connected with a complex (n-parametrical family) of the central nondegenerate hyperquadrics in n-dimensional **affine** **space** are defined and their geometrical sense is found out.
