Centre for networks and collective behaviour


Mathematics of Networks 15

23 September 2016

The 15th Mathematics of Networks meeting (MoN15) took place at the University of Bath, on Friday 23rd September 2016 hosted by the Centre for Networks and Collective Behaviour. MoN is an informal series of meetings that has now been running since 2003. The series encourages interdisciplinary communication in networking research. It is an excellent venue for presenting new ideas or gaining a wider audience for established research. Presentations on any aspect of networking are welcomed, particularly if the techniques or conclusions are applicable in other networking disciplines. Attendance is free of cost.

Information and slides from previous meetings are available here.

Dynamical Networks and Network Dynamics

18-22 January 2016

Many phenomena in the complex world in which we live can be understood in terms of networks of interacting components. Acknowledgement of this fact has led to network models becoming ubiquitous in almost all areas of science, from biology to telecommunication and social sciences. In the mathematical sciences the importance of networks was recognised around the turn of the millennium, when a variety of random graph models were developed which have some of the characteristic features of real-world systems, like heavy-tailed degree distributions, small diameter, or significant clustering. Since then rapid progress has developed on two distinct fronts: On the one hand, combinatorialists and probabilists have developed rigorous techniques to describe the emerging topology of the (by now) classical random graph models like configuration models,inhomogeneous random graphs or preferential attachment networks in considerable detail. On the other hand, applied mathematicians and theoretical physicists have primarily focussed their attention on the dynamical properties of network processes, such as the spread of disease or the dissemination of information.

The objective of this week long meeting was to bring together researchers on networks with a probability or combinatorics background on the one hand, and with an applied mathematics background on the other. Full details can be found here.


Collective Dynamics & Evolving Networks

6-8 July 2015

'Network-type' problems, for example, internet reliability and security, genetic regulation, transportation, utilities and communication infrastructure are one of the emergent themes of 21st century science. Despite their diverse fields of application, and methods of study within those fields, it has become increasingly clear that serious scientific progress can be made by considering commonalities both through abstraction and through quantitative study of datasets. Collective behaviour problems arise in a similarly broad range of situations: obvious examples from the natural world include human crowd dynamics, animal social groups, flocking, herding, swarming and shoaling behaviours, and these descriptions have crossed into many other areas, notably descriptions of financial activity.

The focus of this workshop is on the modelling and analysis of evolving networks and collective dynamics, as well as applications across a wide range of problems including those from physical, biological, financial and social sciences.

Collective Behaviour in Growing Systems

18-19 November 2014

A two-day knowledge-sharing workshop on the subject of collective dynamics in out-of-equilibrium systems driven by growth. Part of the EPSRC Network+ on Emergence and Physics far from Equilibrium.

Growth is an important driver of non-equilibrium dynamics in a wide range of systems. Examples belong to a range of application areas, including bacteria, cancerous tumors, financial markets, cities and even galaxies. Nevertheless, the overarching challenge (both for theoretical and simulation-based research) is typically the same: to understand the interaction between growth mechanisms and the internal dynamics of the system.

Supported by the EPSRC Network+ on Emergence and Physics far from Equilibrium, the purpose of this event was to bring together a community of people who share the same broad research aims, but would not always attend the same workshops.  This is not a traditional conference with talks that exclusively promote recent research. Instead, the goal of the workshop is to cement the idea of a common goal, identify new directions for research and, ideally, nucleate new collaborations.

Uncertainty in Interaction Networks

12 - 13 June 2013

A two day workshop held to mark the external launch of the new Centre, which brought together a diverse international collection of speakers to discuss the quantitative analysis of network models of collective phenomena.

The conference was supported by the London Mathematical Society, and attracted around 100 external and internal participants who heard from speakers addressing problems in protein dynamics, economics, social media, physics and mathematics.

Cake and Networks

15 May 2013

The internal launch of the Centre was celebrated with a collection of short presentations from people working right across the broad spectrum of networks-related activity in Bath. There was coffee, cake and collaborative colleagues explaining what 'networks' mean to them.
