Topological energy of networks
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023Energy is an important network indicator defined by the eigenvalues of an adjacency matrix that includes the neighbor information for each node. This article expands the definition of network energy to include higher-order information between nodes. We use resistance distances to characterize the distances between nodes and order complexes to extract ...

Topology representing networks
Neural Networks, 1994Abstract A Hebbian adaptation rule with winner-take-all like competition is introduced. It is shown that this competitive Hebbian rule forms so-called Delaunay triangulations, which play an important role in computational geometry for efficiently solving proximity problems.

Reliability of network topologies
IEEE INFOCOM '88,Seventh Annual Joint Conference of the IEEE Computer and Communcations Societies. Networks: Evolution or Revolution?, 2003The authors present some analytical results which can be used to compute network reliability. Some simple techniques to make asymptotic approximations based on parameters of the network topology are derived. Explicit reliability formulae are computed for four network topologies, including the star and counterrotating ring.

The Topology of Shareholding Networks
2005We study the statistical properties of the network of shareholding relationships in the Italian stock market (MIB) and in two US stock markets (NYSE and NASDAQ). The networks are found to be scale free a feature which doesn't seem to be in accord with classical theories of portfolio optimization. Several statistical properties differ across markets and

On the topology of overlay-networks
The 11th IEEE International Conference on Networks, 2003. ICON2003., 2004Random-graph models are about to become an important tool in the study of wireless ad-hoc and sensor-networks, peer-to-peer networks, and, generally, overlay-networks. Such models provide a theoretical basis to assess the capabilities of certain networks, and guide the design of new protocols. Especially the recently proposed models for so-called small-

Evolving Topologies for Network Synchronization
2010 Complexity in Engineering, 2010In this paper we describe possible decentralized strategies to adaptively synchronize complex networks of oscillators. Firstly, we review two adaptation strategies for the coupling gains in the network, and then we describe a completely decentralized strategy to select adaptively the network edges.

Topological Analysis of Longitudinal Networks
2013 46th Hawaii International Conference on System Sciences, 2013Longitudinal networks evolve over time through the addition or deletion of nodes and edges. A longitudinal network can be viewed as a single static network that aggregates all edges observed over some time period (i.e., structure of network is fixed), or as a series of static networks observed in different point of time over the entire network ...

Networks such as road networks, utility networks, computer and communication networks and even social networks are the backbone of human civilization. Network analysis enables quantitative measurement of the important criteria suchas delays, ease of routing and fault tolerance, and is required to build efficient and robust networks.

On Network Topology Inference of Social Networks
2019 57th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2019This paper studies topology inference, from agent states, of a directed cyber-social network with opinion spreading dynamics model that explicitly takes confirmation bias into account. The cyber-social network comprises a set of partially connected directed network of agents at the social level, and a set of information sources at the cyber layer.

Complex Network Topologies and Synchronization
2006 IEEE International Symposium on Circuits and Systems, 2006Synchronization in networks with different topologies is studied. We show that for a large class of oscillators there exist two classes of networks; class-A: networks for which the condition of stable synchronous state is /spl sigma//spl gamma//sub 2/ > a, and class-B: networks for which this condition reads /spl gamma//sub N///spl gamma//sub 2/ < b ...
