On Some Applications and Open Problems about (m-Groups)

Galoitica: Journal of Mathematical Structures and Applications, 2022
The generalizations of abelian groups have been studied widely because of their importance in classification theorem and representation. A group G is called an m-power closed group or (m-group) if and only if it has the following property xm ym=zm ∀x,y ∈

Algebraic hulls of solvable groups and exponential iterated integrals on solvmanifolds

Geometriae Dedicata, 2012
We represent the coordinate ring of algebraic hulls (which are the fundamental groups of generalizations of the Malcev completions of nilpotent groups for solvable groups) of solvmanifolds G/Γ by using Miller’s exponential iterated integrals (which are ...

On the existence and properties of left invariant k-symplectic structures on Lie groups with bi-invariant peudo-Riemannian metric

Communications in Algebra, 2023
k-symplectic manifolds are a convenient framework to study classical field theories and they are a generalization of polarized symplectic manifolds. This paper focus on the existence and the properties of left invariant k-symplectic structures on Lie ...

A Jordan–Chevalley decomposition beyond algebraic groups

Journal of the London Mathematical Society, 2022
We prove a decomposition of definable groups in o‐minimal structures generalizing the Jordan–Chevalley decomposition of linear algebraic groups. It follows that any definable linear group G$G$ is a semidirect product of its maximal normal definable ...
