Title: Dense Networks: Sampling and Dynamics.

Abstract: Understanding hidden populations governed by an underlying
network has always been a challenge using standard sampling methods. The
reasons being cost, lack of sampling frame, privacy concerns, and
populations constituting a small proportion. A network is dense if the
number of edges scales quadratically with the number of vertices. In this
talk we shall discuss limitations of a particular sampling procedure
called Respondent Driven Sampling intended to understand hidden
populations and a natural class of dynamics in dense networks arising from
such re-sampling in multi-type population.
