fi(Ric) - Vector Fields on Conformally Flat Spaces

We study the equation of existence of special vector fields, related with the Ricci flows, on conformally flat spaces. We demonstrate that in this case such vector fields exist only in special subprojective spaces ...

Concircular and convergent vector fields on compact spaces with affine connections

Certain properties of torse-forming, concircular and convergent vector fields on spaces with affine connection are studied. Connections of spaces in which such vector fields exist are found. Moreover, examples of m...

Nonseparable closed vector subspaces of separable topological vector spaces

vector spaces E, does the separable space [InlineEquation not available: see fulltext.] have a nonseparable closed vector subspace, where c is the cardinality of the continuum? He provided a partial answer, provin...

Vector Spaces in the Context of Neural Networks.

Input and output signals in the neural network can be understood as vectors. Vector spaces in the neural network can be defined more broadly, which lets you search for similarities with other algebraic structures. This arti...

fi(Ric)-vektor fields in Riemannian spaces

In this paper we study special vector fields in Riemannian spaces, which satisfy to some conditions. We investigate certen properties of these fields and the conditions of their coexistence with concircular vector fields....

Henstock-Kurzweil Integration: Its Relation to Topological Vector-Spaces.

This monograph is devoted to the vector space of equivalence classes of functions which are Henstock-Kurzweil integrable on a compact one-dimensional interval or equivalently, to the vector space P of their primiti...
