$2$ -Neighbor Bootstrap Percolation on Odd Graphs

Ali Mohammadian, Sina Rezaie Zareie, Behruz Tayfeh-Rezaie

The $r$ -neighbor bootstrap percolation process on a graph $G$ is a vertex-activation process that begins with a set of initially active vertices. In each subsequent round, every in…

A search for Hadamard matrices of Williamson type

Hadi Kharaghani, Ali Mohammadian, Behruz Tayfeh-Rezaie

In this article, we consider a special class of Williamson type matrices which we call them near Williamson matrices. They are in fact four $n \times n$ $(- 1, 1)$ -matrices $A, B, C,…
