Comparing alternatives to the fixed degree sequence model for extracting the backbone of bipartite projections. [PDF]

open access: yesSci Rep, 2021
Projections of bipartite or two-mode networks capture co-occurrences, and are used in diverse fields (e.g., ecology, economics, bibliometrics, politics) to represent unipartite networks.

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 ...

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.

Exploring the assortativity-clustering space of a network’s degree sequence [PDF]

open access: green, 2007
Nowadays there is a multitude of measures designed to capture different aspects of network structure. To be able to say if the structure of certain network is expected or not, one needs a reference model (null model).

Graphs with Given Degree Sequence and Maximal Spectral Radius [PDF]

open access: diamond, 2008
We describe the structure of those graphs that have largest spectral radius in the class of all connected graphs with a given degree sequence. We show that in such a graph the degree sequence is non-increasing with respect to an ordering of the vertices ...

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.

Enumeration of graphs with a heavy-tailed degree sequence [PDF]

open access: yes, 2016
In this paper, we asymptotically enumerate graphs with a given degree sequence d=(d_1,...,d_n) satisfying restrictions designed to permit heavy-tailed sequences in the sparse case (i.e. where the average degree is rather small).

On the swap-distances of different realizations of a graphical degree sequence [PDF]

open access: yesCombinatorics, probability & computing, 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 ...

Induced subgraphs in sparse random graphs with given degree sequence

open access: green, 2010
For any $S\subset [n]$, we compute the probability that the subgraph of $\mathcal{G}_{n,d}$ induced by $S$ is a given graph $H$ on the vertex set $S$.
