Some properties of ergodicity coefficients with applications in spectral graph theory

Rachid Marsli, Frank J. Hall

The main result is Corollary 2.9 which provides upper bounds on, and even better, approximates the largest non-trivial eigenvalue in absolute value of real constant row-sum matrice…

On the prime decomposition of integers of the form $(z^{n} - y^{n}) / (z - y)$

Rachid Marsli

In this work, the author shows a sufficient and necessary condition for an integer of the form $(z n - y^{n}) / (z - y)$ to be divisible by some perfect $m t h$ power $p$ , where $p$ is an odd…
