Curvature of 2nd type induced on plane distribution
In many-dimensional projective space the plane distribution is considered. The curvature of group connection of 2-nd type, induced by composite clothing of plane distribution, is constructed. It is proved, that a immovability of Cartan’s plane and Bortolotti’s hyperplane in case of holonomic distribution attracts the vanishing of curvature tensor of 2-nd type.

Strongly mutual threefold distributions of projective space
... of a special class ( -distribution) of the regular threefold distributions ( -distribution ) of the projective space consisting of a basic distribution of the 1st kind of r-dimensional planes are equipped with the distribution of the 1st kind of m-dimensional planes and equip distribution 1st the first kind of hyperplane elements (hyperplanes) with the ratio of the incidence of the corresponding elements in the common center is considered in this article. In this paper, these three distributions is considered as a immersed ...

A semicanonical normal affine connection associated with the distribution
In manydimensional projective space distribution of planes is considered. The way of giving normal generalized affine connection associated with the distribution is proposed. It is shown that this connection is given by connection tensor and normal linear connection object. They define its curvature and ...
A study of the statistic properties of the distribution of thermokarst lakes in the West Siberian cryolithic zone on the basis of satellite images
The location of thermokarst lakes on the research territory in the permafrost zone of Western Siberia is identified with the use of satellite images. The statistical data analysis shows that the empirical laws of spatial distribution of the lake centers on the plane correspond to the uniform distribution law.
