Distance regularity in direct-product graphs

Applied Mathematics Letters, 2000
The direct product (also called Kronecker product, tensor product, and cardinal product) G × H of distance-regular graphs is investigated. It is demonstrated that the product is distance-regular only when G and H are very restricted distance-regular ...

The Direct Product of Matrices

The Mathematical Gazette, 1953
The concept of the direct product is widely used in the theory of groups, algebras, vector spaces and allied topics, but its use as a manipulative tool in matrix algebra is less common. The present note shows how the direct product of matrices arises in elementary work, derives some of its more important properties, and gives some ...

Latin interchanges and direct products.

Ars Comb., 2002
Summary: In this paper we focus on the identification of Latin interchanges in Latin squares which are the direct product of Latin squares of smaller orders. The results we obtain on Latin interchanges will be used to identify critical sets in direct products. This work is an extension of research carried out by \textit{D. R. Stinson} and \textit{G. H.

Direct Sums and Direct Products

2015
The concept of direct sum is of utmost importance for the theory. This is mostly due to two facts: first, if we succeed in decomposing a group into a direct sum, then it can be studied by investigating the summands separately, which are, in numerous cases, simpler to deal with.

On Direct Products of Abelian Groups

Canadian Journal of Mathematics, 1970
In this paper we investigate the properties of the product (or complete direct sum) of torsion Abelian groups. The chief results concern products of Abelian primary groups (p-groups). Given a set of p-groups, [Gλ], over an index set Λ, the product of these groups is written λλ∈ΔGλ, the torsion subgroup of the product of these p-groups is written T[λGλ],

Product properties and their direct verification

Acta Informatica, 1983
The paper presents a family of properties of programs, called product (and power) properties, for which the verification method of Floyd and Hoare are inconvenient. A (semantically) complete alternative method is proposed' The paper presents the method in both the endogenous and exogenous versions and applies them to examples. Semantic completeness and
