#### Strongly associated threefold distributions of projective space

Abstract
Construction of a general theory of a special class (SH -distribution) of the regular threefold distributions (H -distribution) of the projective space Pn consisting of a basic distribution of the 1st kind of r-dimensional planes r are equipped with the distribution of the 1st kind of m-dimensional planes Mm (m r) and equip distribution 1st the first kind of hyperplane elements (hyperplanes) Hn-1 with the ratio of the incidence of the corresponding elements in the common center X: X M H is considered in this article. In this paper, these three distributions is considered as a immersed manifold. By virtue of the SH -distribution structure in the geometry of the manifold are similar to some of the facts from the geometry of m-dimensional linear elements (n 1)-dimensional linear elements and hyperband distribution. However, the analogy does not relate to the geometry of the base only or equipping distributions taken separately. Research was carried out by G. F. Laptev method. Determinations of the H -distributionand existence theorems are given in the frame of zero order. Requiring that Λ-, L-, E-distribution were mutually associated we introduce a special class of threefold distributions, which we call strongly associated distributions or SH -distribution. Definition of SH -distribution is given in the frame of the 1st order and the existence theorem is proved.
