On -Matrix Product Factorization of graphs
Farzad Maghsoudi, Bobby Miraftab, Sho Suda
We introduce an approximate version of matrix product factorization for graphs. A simple graph on vertices is said to admit an -matrix product factorization if…

Constructions of -designs from weighing matrices and association schemes
Gary Greaves, Sho Suda
We provide a method to construct -designs from weighing matrices and association schemes. One instance of our method can produce a -design from any (symmetric or skew-symmetr…

On Matrix Product Factorization of graphs
Farzad Maghsoudi, Babak Miraftab, Sho Suda
In this paper, we explore the concept of the ``matrix product of graphs," initially introduced by Prasad, Sudhakara, Sujatha, and M. Vinay. This operation involves the multiplicati…
