Network coding is a relatively new subject, exploiting the fact that the capacity of a network to carry information can be higher than its capacity for regular commodities if the vertices (or edges) of the network have some processing power. The famous “butterfly network”, shown on below, is the simplest example of this paradigm.

In conjunction with EPSRC (grant EP/H016015/1), we are having a two-day workshop on the topic Information Flows and Information Bottlenecks on 11-12 September 2012. The main aim of the workshop is to communicate problems and challenges in multi-user information theory and Network Coding to a wider community including mathematicians. The first day will consist of tutorials to bring participants up to speed in the area; the second will be a conference at which some of the leading researchers will give presentations.
Information about the workshop will be kept here. We will add further details as they become available.
In the meantime, please email Søren Riis or Peter Cameron if you are interested in attending the workshop.
