Insights on the homogeneous $3$ -local representations of the twin groups

Mohamad N. Nasser

We provide a complete classification of the homogeneous $3$ -local representations of the twin group $T_{n}$ , the virtual twin group $V T_{n}$ , and the welded twin group $W T_{n}$ , for all…

Algebraic and topological aspects of the singular twin group and its representations

Mohamad N. Nasser, Nafaa Chbili

In this article, we introduce the singular twin monoid and its corresponding group, constructed from both algebraic and topological perspectives. We then classify all complex homog…

On the classification and irreducibility of $2$ -local representations of the twin group $T_{n}$

Taher I. Mayassi, Mohamad N. Nasser

We investigate the homogeneous $2$ -local representations of the twin group $T_{n}$ for all integers $n ⩾ 2$ . A complete classification is obtained, yielding three distinct fam…

On representations of the multi-virtual braid group $M_{k} V B_{n}$ and the multi-welded braid group $M_{k} W B_{n}$

Vaibhav Keshari, Mohamad N. Nasser, Madeti Prabhakar

This paper classifies complex homogeneous $2$ -local representations of the multiple virtual braid group $M_{k} V B_{n}$ into $GL_{n} (C)$ for $n \geq 3$ and $k > 1$ , showing…

On the irreducibility of singular braid group representations

Mohamad N. Nasser

In this article, we investigate the irreducibility of representations of the singular braid group on $n$ strands, denoted by $S B_{n}$ . We first show that all representations $ρ: SB_2…

Twin groups representations

Mohamad N. Nasser

We construct two representations of the twin group $T_{n}, n \geq 2$ , namely $η_{1} : T_{n} \to Aut (F_{n})$ and $η_2: T_n \rightarrow \text{GL}_n(\mathbb{Z}[t^{\pm 1}…

Matrix representations of the twisted virtual braid group and its extensions

Mohamad N. Nasser, Vaibhav Keshari, Madeti Prabhakar

This paper classifies complex local representations of the twisted virtual braid group, $T V B_{2}$ , into $GL_{3} (C)$ . It shows that such representations fall into eigh…

On extensions of the standard representation of the braid group to the singular braid group

Mohamad N. Nasser

For an integer $n \geq 2$ , set $B_{n}$ to be the braid group on $n$ strands and $S B_{n}$ to be the singular braid group on $n$ strands. $S B_{n}$ is one of the important group extensions…

Local Representations of the Flat Virtual Braid Group

Mohamad N. Nasser, Mohammad Y. Chreif, Malak M. Dally

We prove that any complex local representation of the flat virtual braid group, $F V B_{2}$ , into $G L_{2} (C)$ , has one of the types $λ_{i} : F V B_{2} \to G L_{2} (C)$ , $1…

Classification of Homogeneous Local Representations of the Singular Braid Monoid

Taher I. Mayassi, Mohamad N. Nasser

For a natural number $n$ , denote by $B_{n}$ the braid group on $n$ strings and by $S M_{n}$ the singular braid monoid on $n$ strings. $S M_{n}$ is one of the most important extensions of $…
