Query: Multicores-periphery structure in networks   Many real-world networks exhibit a multicores-periphery structure, with
densely connected vertices in multiple cores surrounded by a general periphery
of sparsely connected vertices. Identification of the multicores-periphery
structure can provide a new lens to understand the structures and functions of
various real-world networks. This paper defines the multicores-periphery
structure and introduces an algorithm to identify the optimal partition of
multiple cores and the periphery in general networks. We demonstrate the
performance of our algorithm by applying it to a well-known social network and
a patent technology network, which are best characterized by the
multicores-periphery structure. The analyses also reveal the differences
between our multicores-periphery detection algorithm and two state-of-the-art
algorithms for detecting the single core-periphery structure and community
structure.
