Line Cut Vertex Digraphs Of Digraphs

open access: yes, 2015
In this paper we define the digraph valued function (digraph operator) namely the line cut vertex digraph Lc(D) of a digraph D. The problem of reconstructing a digraph from its line cut vertex digraph is presented. Also, outer planarity and maximal outer planarity properties of these digraphs are discussed.

Finite-dimensional flexible algebras associated with directed and weighted CW complexes

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we study a link between directed and weighted CW complexes (also called configurations) and flexible algebras determining which configurations are associated with those algebras.

Spectra of digraphs

open access: yesLinear Algebra and its Applications, 2010
AbstractIn this primarily expository paper we survey classical and some more recent results on the spectra of digraphs, equivalently, the spectra of (0,1)-matrices, with emphasis on the spectral radius.
