Log-concavity and LC-positivity
Yi Wang, Yeong-Nan Yeh
A triangle of nonnegative numbers is LC-positive if for each , the sequence of polynomials is -log-concave. It is double…
A deterministic small-world network created by edge iterations
Zhongzhi Zhang, Lili Rong, Chonghui Guo
Small-world networks are ubiquitous in real-life systems. Most previous models of small-world networks are stochastic. The randomness makes it more difficult to gain a visual under…
Multipartite Entanglement Measure
Chang-shui Yu, He-shan Song
In this paper, we generalize the residual entanglement to the case of multipartite states in arbitrary dimensions by making use of a new method. Through the introduction of a speci…
Crossings and Nestings of Matchings and Partitions
William Y. C. Chen, Eva Y. P. Deng, Rosena R. X. Du +2
We present results on the enumeration of crossings and nestings for matchings and set partitions. Using a bijection between partitions and vacillating tableaux, we show that if we…
Clustering Categorical Data Streams
Zengyou He, Xiaofei Xu, Shengchun Deng +1
The data stream model has been defined for new classes of applications involving massive data being generated at a fast pace. Web click stream analysis and detection of network int…
