Temporal Aspects of Dynamic Role Assignment
A helpful abstraction of a group of agents is a set of interacting roles, or sets of normative behaviors, that the agents can assume. An important characteristic of real-world agen...

Characterizing continuous time random walks on time varying graphs
In this paper we study the behavior of a continuous time random walk (CTRW) on a stationary and ergodic time varying dynamic graph. We establish conditions under which the CTRW is...
