and the information flow within it. In our recent work [7], we showed that a particular core-
periphery decomposition using topological collapses has (a) structural properties desired in
the decomposition, and (b) communal properties in the peripheral components. In this
paper, we investigate the role of the core in the information flow. Specifically, we study time-
evolving collaborative networks and quantify the influence of the core nodes in forming new …
