Revisiting the action of a subgroup of the modular group on imaginary quadratic number fields

Abdulaziz Deajim

Consider the modular group $\mbox{PSL}(2,\mathbb{Z})=\langle x, \, y \,|\, x^2=y^3=1\rangle$ generated by the transformations and . Let b…

On Self-Orthogonality and Self-Duality of Matrix-Product Codes over Commutative Rings

Abdulaziz Deajim, Mohamed Bouye

Let be a commutative ring with identity. The paper studies the problem of self-orthogonality and self-duality matrix-product codes (MPCs) over . Some methods as well as spec…

Matrix-Product Codes over Commutative Rings and Constructions Arising from -Codes

Mhammed Boulagouaz, Abdulaziz Deajim

A well-known lower bound (over finite fields and some special finite commutative rings) on the Hamming distance of a matrix-product code (MPC) is shown to remain valid over any com…

On the number of orbits arising from the action of $\mbox{PSL}(2,\mathbb{Z})$ on imaginary quadratic number fields

Muhammad Aslam, Abdulaziz Deajim

For square-free positive integers , we study the action of the modular group $\mbox{PSL}(2,\mathbb{Z})$ on the subsets $\{\,\frac{a+\sqrt{-n}}{c}\in \mathbb{Q}(\sqrt{-n})\, | \,…
