K-Means Community Detection Algorithm Based on Density Peaks [PDF]
EntropyThe identification of community structure is pivotal for understanding the functional characteristics of complex networks. To address the limitations of most existing community detection algorithms, which often require predefining the number of ...

Vacuum Solutions of Classical Gravity on Cyclic Groups from Noncommutative Geometry [PDF]
, 2001 Based on the observation that the moduli of a link variable on a cyclic group modify Connes' distance on this group, we construct several action functionals for this link variable within the framework of noncommutative geometry.

A strong invariance principle for associated random fields [PDF]
, 2005 In this paper we generalize Yu's [Ann. Probab. 24 (1996) 2079-2097] strong invariance principle for associated sequences to the multi-parameter case, under the assumption that the covariance coefficient u(n) decays exponentially as n\to \infty.

The random conductance model with Cauchy tails [PDF]
, 2010 We consider a random walk in an i.i.d. Cauchy-tailed conductances environment. We obtain a quenched functional CLT for the suitably rescaled random walk, and, as a key step in the arguments, we improve the local limit theorem for $p^{\omega}_{n^2t}(0,y)$
