Degree sequence for k-arc strongly connected multiple digraphs
Let D be a digraph on [Formula: see text] . Then the sequence [Formula: see text] is called the degree sequence of D. For any given sequence of pairs of integers [Formula: see text] , if there exists a k-arc strongly connected digraph D such that d is the degree sequence of D, then d is realizable a...

description | Let D be a digraph on [Formula: see text] . Then the sequence [Formula: see text] is called the degree sequence of D. For any given sequence of pairs of integers [Formula: see text] , if there exists a k-arc strongly connected digraph D such that d is the degree sequence of D, then d is realizable and D is a realization of d. In this paper, characterizations for k-arc-connected realizable sequences and realizable sequences with arc-connectivity exactly k are given. |
