Degree sequence for k-arc strongly connected multiple digraphs [PDF]

open access: yesJournal of Inequalities and Applications, 2017
Let D be a digraph on { v 1 , … , v n } $\{v_{1},\ldots, v_{n}\}$ . Then the sequence { ( d + ( v 1 ) , d − ( v 1 ) ) , … , ( d + ( v n ) , d − ( v n ) ) } $\{ (d^{+}(v_{1}), d^{-}(v_{1})), \ldots, (d^{+}(v_{n}), d^{-}(v_{n}))\}$ is called the degree ...

On the Swap-Distances of Different Realizations of a Graphical Degree Sequence [PDF]

open access: green, 2013
One of the first graph theoretical problems which got serious attention (already in the fifties of the last century) was to decide whether a given integer sequence is equal to the degree sequence of a simple graph (or it is {\em graphical} for short ...

Controllability of deterministic networks with the identical degree sequence. [PDF]

open access: yesPLoS ONE, 2015
Controlling complex network is an essential problem in network science and engineering. Recent advances indicate that the controllability of complex network is dependent on the network's topology.

Degree Sequences of Monocore Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A k-monocore graph is a graph which has its minimum degree and degeneracy both equal to k. Integer sequences that can be the degree sequence of some k-monocore graph are characterized as follows. A nonincreasing sequence of integers d0, . . . , dn is the

Constructing and sampling partite, 3-uniform hypergraphs with given degree sequence. [PDF]

open access: yesPLoS ONE
Partite, 3-uniform hypergraphs are 3-uniform hypergraphs in which each hyperedge contains exactly one point from each of the 3 disjoint vertex classes. We consider the degree sequence problem of partite, 3-uniform hypergraphs, that is, to decide if such ...

Efficient and exact sampling of simple graphs with given arbitrary degree sequence. [PDF]

open access: yesPLoS ONE, 2010
Uniform sampling from graphical realizations of a given degree sequence is a fundamental component in simulation-based measurements of network observables, with applications ranging from epidemics, through social networks to Internet modeling.

Degree Sequence Index Strategy [PDF]

open access: yes, 2012
We introduce a procedure, called the Degree Sequence Index Strategy (DSI), by which to bound graph invariants by certain indices in the ordered degree sequence.

Cyclic Hypergraph Degree Sequences [PDF]

open access: green, 2017
The problem of efficiently characterizing degree sequences of simple hypergraphs is a fundamental long-standing open problem in Graph Theory. Several results are known for restricted versions of this problem. This paper adds to the list of sufficient conditions for a degree sequence to be {\em hypergraphic}.

The component sizes of a critical random graph with given degree sequence [PDF]

open access: green, 2010
Consider a critical random multigraph $\mathcal{G}_n$ with $n$ vertices constructed by the configuration model such that its vertex degrees are independent random variables with the same distribution $\nu$ (criticality means that the second moment of ...

Tribonacci graphs [PDF]

open access: yesITM Web of Conferences, 2020
Special numbers have very important mathematical properties alongside their numerous applications in many fields of science. Probably the most important of those is the Fibonacci numbers.
