Exponential synchronization of the high-dimensional Kuramoto model with identical oscillators under digraphs [PDF]

open access: yesat - Automatisierungstechnik, 2018
For the Kuramoto model and its variations, it is difficult to analyze the exponential synchronization under the general digraphs due to the lack of symmetry.

Antistrong digraphs

open access: yesJournal of Combinatorial Theory, Series B, 2017
An antidirected trail in a digraph is a trail (a walk with no arc repeated) in which the arcs alternate between forward and backward arcs. An antidirected path is an antidirected trail where no vertex is repeated. We show that it is NP-complete to decide whether two vertices $x,y$ in a digraph are connected by an antidirected path, while one can decide

Asymptotic enumeration of Cayley digraphs [PDF]

open access: yesIsrael Journal of Mathematics, 2018
In this paper we show that almost all Cayley digraphs have automorphism group as small as possible; that is, they are digraphical regular representations (DRRs).

Girth in digraphs [PDF]

open access: yesJournal of Graph Theory, 1980
AbstractFor an integer k > 2, the best function m(n, k) is determined such that every strong digraph of order n with at least m(n, k) arcs contains a circuit of length k or less.

Processing Large Outliers in Arrays of Observations

open access: yesMathematics, 2022
The interest in large or extreme outliers in arrays of empirical information is caused by the wishes of users (with whom the author worked): specialists in medical and zoo geography, mining, the application of meteorology in fishing tasks, etc.

Distributed Convex Optimization with Inequality Constraints over Time-Varying Unbalanced Digraphs [PDF]

open access: yesIEEE Transactions on Automatic Control, 2016
This paper considers a distributed convex optimization problem with inequality constraints over time-varying unbalanced digraphs, where the cost function is a sum of local objective functions, and each node of the graph only knows its local objective and

Infinite digraphs isomorphic with their line digraphs

open access: yesJournal of Combinatorial Theory, Series B, 1976
In this paper we give a structural characterization of the digraphs that are isomorphic with their line digraphs.

A Note on the Concept of Time in Extensive Games

open access: yesMathematics, 2022
Using the concept of informational digraphs, we propose a “no redundant information sets” property that can characterize the exact class of extensive games which can be time structured. Our result can be applied to define time-dependent solution concepts
