On strongly reversible elements in the Riordan group

Roksana Słowik, Tejbir Lohan

An element of a group is called \emph{reversible} if it is conjugate to its inverse, and \emph{strongly reversible} if it can be expressed as a product of two involutions. We study…

Real characters and real classes of $GL_{2}$ and $GU_{2}$ over discrete valuation rings

Archita Gupta, Tejbir Lohan, Pooja Singla

Let $o$ be the ring of integers of a non-archimedean local field with residue field of odd characteristic, $p$ be its maximal ideal and let $\mathfrak{o}_\ell…

Linear maps preserving product of involutions

Chi-Kwong Li, Tejbir Lohan, Sushil Singla

An element of the algebra $M_{n} (F)$ of $n \times n$ matrices over a field $F$ is called an involution if its square equals the identity matrix. Gustafson, Halmos,…

Strongly real adjoint orbits of complex symplectic Lie group

Tejbir Lohan, Chandan Maity

We consider the adjoint action of the symplectic Lie group $Sp (2 n, C)$ on its Lie algebra $sp (2 n, C)$ . An element $X \in \mathfrak{sp}(2n,\mathb…

Product of two involutions in quaternionic special linear group

Krishnendu Gongopadhyay, Tejbir Lohan, Chandan Maity

An element of a group is called reversible if it is conjugate to its own inverse. Reversible elements are closely related to strongly reversible elements, which can be expressed as…

Algebraic characterization of reversibility in the quaternionic Möbius group

Krishnendu Gongopadhyay, Tejbir Lohan, Abhishek Mukherjee

An element of a group is called \emph{reversible} if it is conjugate to its inverse. While reversibility in the quaternionic Möbius group $PSL (2, H)$ has tradition…

Strongly reversible classes in $SL (n, C)$

Krishnendu Gongopadhyay, Tejbir Lohan, Chandan Maity

An element of a group is called $strongly reversible$ or $strongly real$ if it can be expressed as a product of two involutions. We provide necessary and sufficie…

Reversibility and Real Adjoint Orbits of Linear Maps

Krishnendu Gongopadhyay, Tejbir Lohan, Chandan Maity

We extend classical results on the classification of reversible elements of the group $GL (n, C)$ (and $GL (n, R)$ ) to $\mathrm{GL}(n, \mathbb{H})…

Classification and Decomposition of Quaternionic Projective Transformations

Sandipan Dutta, Krishnendu Gongopadhyay, Tejbir Lohan

We consider the projective linear group $PSL (3, H)$ . We have investigated the reversibility problem in this group and use the reversibility to offer an algebraic c…

Reversibility of Affine Transformations

Krishnendu Gongopadhyay, Tejbir Lohan, Chandan Maity

An element $g$ in a group $G$ is called reversible if $g$ is conjugate to $g^{- 1}$ in $G$ . An element $g$ in $G$ is strongly reversible if $g$ is conjugate to $g^{- 1}$ by an in…

Limit sets of cyclic quaternionic Kleinian groups

Sandipan Dutta, Krishnendu Gongopadhyay, Tejbir Lohan

In this paper, we consider the natural action of $SL (3, H)$ on the quaternionic projective space $P_{H}^{2}$ . Under this action, we investigate l…

Real adjoint orbits of special linear groups

Krishnendu Gongopadhyay, Tejbir Lohan, Chandan Maity

Let $G$ be a Lie group with Lie algebra $g$ . An element $X \in g$ is called $Ad_{G}$ -real if $- X = g X g^{- 1}$ for some $g \in G$ . Moreover, if $…

Reversibility of Hermitian Isometries

Krishnendu Gongopadhyay, Tejbir Lohan

An element $g$ in a group $G$ is called reversible (or real) if it is conjugate to $g^{- 1}$ in $G$ , i.e., there exists $h$ in $G$ such that $g^{- 1} = h g h^{- 1}$ . The element $g$ is ca…
