A spectral characterization of the s-clique extension of the square grid graphs
Sakander Hayat, Jack H. Koolen, Muhammad Riaz
In this paper we show that for integers , , any co-edge-regular graph which is cospectral with the -clique extension of the -grid is the -clique ex…
Some inequalities on the norms of special matrices with generalized Tribonacci and generalized Pell Padovan sequences
Zahid Raza, Muhammad Riaz, Muhammad Asim Ali
In this paper some properties of generalized tribonacci and generalized Padovan sequence are presented. Also the Euclidean norms of circulant, -circulant, semi-circulant and Han…
A note on the action of on the ring
M. Aslam Malik, Muhammad Riaz
We know that is a finite field for a prime number . Let be arbitrary natural numbers and let $\mathbb{Z}^m_n= \mathbb{Z}_n \times\mathbb{Z}_n\times...\times…
Equivalent Binary Quadratic Form and the Extended Modular Group
M. Aslam malik, Muhammad Riaz
Extended modular group , where $ R:z\rightarrow -\bar{z}, \sim T:z\rightarrow\frac{-1}{z},\simU:z\rightarrow\frac{-1}{z +1} $, has been u…
Orbits of $\QQ^*(\sqrt{n})$ under the action of Modular Group
M. Riaz, M. Aslam Malik
Coset diagrams have been used to study quotients, orbits, subgroups and structure of the finitely generated groups. In this paper we use coset diagrams and modular arithmetic to de…
G-subsets and G-orbits of Q(sqrt n) under action of the modular group
M. Aslam Malik, M. Riaz
It is well known that represents the modular group , where are linear fractiona…
