A Bianchi type-III cosmological model with self-similarity symmetry is investigated in cases with perfect fluid distribution and a cosmic string cloud. We show that this model admits a non-trivial homothetic vector field which possess non-null homoth

Maize is an important grain crop with high nutritional value. An effective transformation system is crucial for the genetic improvement of maize traits, but many important maize inbred lines remained recalcitrant to transformation. In this study, we

The paper studies the three-parameter geometric image of the line - a complex of line of three-dimensional space of the flag. It identifies the main forms that depend linearly on three basic parameters diferentials. The expression of the main correla

The conditions for the existence of additional algebraic first integrals of the system of equations of motion of an absolutely solid material object in the Lobachevsky three-dimensional space according to E. T. Whittaker are given. It is assumed that

A Koszul-Vinberg manifold is a manifold $M$ endowed with a pair $(\nabla,h)$ where $\nabla$ is a flat connection and $h$ is a symmetric bivector field satisfying a generalized Codazzi equation. The geometry of such manifolds could be seen as a type o

Principal angles are used to define an angle bivector of subspaces, which fully describes their relative inclination. Its exponential is related to the Clifford geometric product of blades, gives rotors connecting subspaces via minimal geodesics in G

In this paper we introduce and investigate some properties of fuzzy sub-vector spaces and fuzzy sub-bivector spaces by using t-norms and consider some of their properties and structured characteristics. Also we define some concepts as intersection,
