• Giving the 1st order affine connection by means of the 2nd order vector-valued forms

  ... 1st order tangent space to a manifold. It is shown that affine connection in bundle of tangent lin-ear frames defines linear operator from 1st order cotangent space (space of forms of degree 1) in cotangent space of 2nd order. It is proved that affine connection in bundle of tangent linear frames defines horizontal linear operator (2nd order hor-izontal horizontal-valued form of 1st order affine connection) in 2nd order tan-gent bundle. It is shown that the second usual differential of a point of a mani-fold it is possible to present ...

• 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 torsion tensors. Semicanonical case is investigated when subtensor of the connection tensor vanishes. Two notions are involved: non-degeneration tensor of torsion and semiholonomical distribution. It is ...

• About generalizations of the Cartan projective connection on smooth manifold

  The Laptev projective structure of the 1st order presented a fibering of special linear coframes with multidimensional gluing is considered. The Laptev linear connection by means of the object containing a tensor is set in this fibering. If the tensor vanishes we have preprojective connection from which canonical connection is marked out. The Cartan projective connection and its canonical version are obtained ...

• Fundamental-group connections, induced by composite clothing of family of centered planes in projective space

  ... clothing of such a family induces three-parameter bunch of bundles of fundamental-group connections. One induced connection is allocated from each of this bundles. Coincidence conditions of the received connections and geometrical interpretation of the linear sub connections is given. 1. Белова О. О.

• Analysis methodology for the relationship between the water flow and river levels by determining the dependence

  The article contains all the available data on average monthly discharges and water levels for the rivers under study, that provided the background for the hydrological series of these characteristics which are found to be in a close stochastic connection. Linear regression equations connect the average month­ly discharges and water levels in the rivers under study. They also provide for the graphs of the relationship between the considered values, and the bounda­ries of their confidence intervals were ...
