### Birth and death processes in graphs and networks

The study of the evolution of graphs and networks with time has developed enormously in recent years – see Dorogovtsev & Mendes (2001). Many models for the evolution of graphs have been proposed to reflect various properties of real world graphs such as the Web, citation graphs, and biological and social networks.

Recently, Fayolle, Krikun & Lasgouttes (2004) and Deo & Cami (2005, 2007) have studied the evolution of graphs and networks via birth and death processes.

The aim of this research project is to build and analyze models of evolution of graphs and networks using continuous and discrete time birth and death processes, in which both edges and vertices can be born or die at each time .
