### Singular and N onsingular Circulant Asymmetric Digraphs

Discipline: Mathematics, Formal Sciences

#### Abstract:

This paper describes two special types of digraphs which arc r-regular, circulant and asymmetric. These graphs are denoted by Crn 'and dCn. Specifically, this paper shows which of these special classes of r-egular, asymmetric and circulant digraphs are singular and which are non-singular.
