Para-f-Lie groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Special para-f-structures on Lie groups are studied. It is shown that every para-f-Lie group G is the quotient of the product of an almost product Lie group and a Lie group with trivial para-f-structure by a discrete subgroup.

2 × 2 Matrices: Manifolds, Realizations, Applications

open access: yesApplied Sciences, 2021
Both geometric and wave optical models, as well as classical and quantum mechanics, realize linear transformations with matrices; for plane optics, these are 2×2 and of unit determinant.

Star product on the Lie coalgebra and its application for calculation of quantum integrals of motion

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
The article gives an algorithm for constructing quantum integrals of motion on the basis of well-known classic integrals.To construct quantum integrals, we apply star product of the operators' symbols, which is used in the quantization theory.A non ...

Lie algebras whose Lie groups have negative sectional curvature

open access: yesRevista Integración, 2022
The aim of this work is to completely describe two families of Lie algebras whose Lie groups have negative sectional curvature. The first family consists of Lie algebras satisfying the following property: given any two vectors in the Lie algebra, the ...

On Lie rings of torsion groups

open access: yesBulletin of Mathematical Sciences, 2016
We prove that the Lie ring associated to the lower central series of a finitely generated residually-p torsion group is graded nil.

Differentiable semigroups are Lie groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
We present here a modern, detailed proof to the following theorem which was introduced by Garrett Birkhoff [1] in 1938. If S is a local semigroup with neighborhood of 1 homeomorphic to a Banach space and with multiplication strongly differentiable at 1 ...

Further results on q-Lie groups, q-Lie algebras and q-homogeneous spaces

open access: yesSpecial Matrices, 2021
We introduce most of the concepts for q-Lie algebras in a way independent of the base field K. Again it turns out that we can keep the same Lie algebra with a small modification.
