# Network theory: an overview

John Baez ( University of California, Riverside )

- 14:00 21st February 2014 ( week 5, Hilary Term 2014 )Lecture Theatre B, Department of Computer Science

Nature and the world of human technology are full of networks. People like to draw diagrams of networks: flow charts, electrical circuit diagrams, signal flow diagrams, Bayesian networks,

Feynman diagrams and the like. Mathematically minded people know that in principle these diagrams fit into a common framework: category theory. But we are still far from a unified theory of networks. This talk will be an overview, and will be followed by a mini-course of 3 further lectures exploring the ideas in detail.
