 School of Mathematics Title: Disjoint weighing matrices Author(s): Behruz Tayfeh-Rezaie (Joint with H. Kharaghani and Sh. Suda) Status: To Appear Journal: J. Algebraic Combin. Supported by: IPM
Abstract:
The notion of disjoint weighing matrices is introduced as a generalization of orthogonal designs. A recursive construction along with a computer search lead to some infinite classes of disjoint weighing matrices, which in turn are shown to form commutative association schemes with 3 or 4 classes.
