-Neighbor Bootstrap Percolation on Odd Graphs

Ali Mohammadian, Sina Rezaie Zareie, Behruz Tayfeh-Rezaie

The -neighbor bootstrap percolation process on a graph 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 -matrices $A, B, C,…

On saturation numbers of complete multipartite graphs and even cycles

Ali Mohammadian, Milad Poursoltani, Behruz Tayfeh-Rezaie

Given positive integer and graph , the saturation number is the minimum number of edges in an edge-maximal -free graph on vertices. In this paper…

Bootstrap percolation on the Hamming graphs

Meysam Miralaei, Ali Mohammadian, Behruz Tayfeh-Rezaie

The -edge bootstrap percolation on a graph is an activation process of the edges. The process starts with some initially activated edges and then, in each round, any inactive ed…

On the classification of skew Hadamard matrices of order 36 and related structures

Makoto Araya, Masaaki Harada, Hadi Kharaghani +2

Two skew Hadamard matrices are considered {\sf SH}-equivalent if they are similar by a signed permutation matrix. This paper determines the number of {\sf SH}-inequivalent skew Had…

Weak saturation numbers in random graphs

Olga Kalinichenko, Meysam Miralaei, Ali Mohammadian +1

For two given graphs and , a graph is said to be weakly -saturated if is a spanning subgraph of which has no copy of as a subgraph and one can ad…
