A linear algebraic approach to orthogonal arrays and Latin squares
A. A. Khanban, M. Mahdian, E. S. Mahmoodian
To study orthogonal arrays and signed orthogonal arrays, Ray-Chaudhuri and Singhi (1988 and 1994) considered some module spaces. Here, using a linear algebraic approach we define a…
Possible volumes of t-(v, t + 1) Latin trades
E. S. Mahmoodian, M. S. Najafian
The concept of - trades of block designs previously has been studied in detail. See for example A. S. Hedayat (1990) and Billington (2003). Also Latin trades have been st…
On the spectrum of the forced matching number of graphs
Peyman Afshani, Hamed Hatami, Ebadollah S. Mahmoodian
Let be a graph that admits a perfect matching. A {\sf forcing set} for a perfect matching of is a subset of , such that is contained in no other perfect matc…
On the existence of k-homogeneous Latin bitrades
Behrooz Bagheri Gh., E. S. Mahmoodian
Following the earlier work on {homogeneous Latin bitrades by Cavenagh, Donovan, and Dr'apal (2003 and 2004) Bean, Bidkhori, Khosravi, and E. S. Mahmoodian (2005) we prove the follo…
