Adamant digraphs

More skew-equienergetic digraphs

Two digraphs of same order are said to be skew-equienergetic if their skew energies are equal. One of the open problems proposed by Li and Lian was to construct non-cospectral skew-equienergetic digraphs on n vertices. Recently this problem was solved by Ramane et al. In this  paper, we give some new methods to construct new skew-equienergetic digraphs.

S-2-(Adamant-1-yl)-4-methyl­phenyl N,N-dimethyl­thio­carbamate

The title compound, C(20)H(27)NOS, was obtained from the corresponding O-thio-carbamate. The structure features a C=O bond distance of 1.209 (2) Å and an sp(3)-hybridized S atom [C-S-C = 101.66 (1)°]. The steric bulk of the 1-adamantyl substituent on the 2-position of the aromatic ring is reflected in the S-C-C-C torsion angle [-7.5 (3)°].

From subKautz digraphs to cyclic Kautz digraphs

Kautz digraphs K(d, `) are a well-known family of dense digraphs, widely studied as a good model for interconnection networks. Closely related with these, the cyclic Kautz digraphs CK(d, `) were recently introduced by Böhmová, Huemer and the author, and some of its distance-related parameters were fixed. In this paper we propose a new approach to cyclic Kautz digraphs by introducing the family ...

Block Line Cut Vertex Digraphs of Digraphs

In this paper, the digraph valued function(digraph operator), namely the block line cut vertex digraph BLC(D) of a digraph D is defined, and the problem of reconstructing a digraph from its block line cut vertex digraph is presented. Outer planarity, maximal outer planarity, and minimally non-outer planarity properties of these digraphs are discussed.
