Deformation of Marchenko-Pastur distribution for the correlated time series
Masato Hisakado, Takuya Kaneko
We study the eigenvalue of the Wishart matrix, which is created from a time series with temporal correlation. When there is no correlation, the eigenvalue distribution of the Wisha…
Information cascade on networks and phase transitions
Masato Hisakado, Kazuaki Nakayama, Shintaro Mori
Herein, we consider a voting model for information cascades on several types of networks -- a random graph, the Barabási-Albert(BA) model, and lattice networks -- by using one para…
Self-exciting negative binomial distribution process and critical properties of intensity distribution
Kotaro Sakuraba, Wataru Kurebayashi, Masato Hisakado +1
We study the continuous time limit of a self-exciting negative binomial process and discuss the critical properties of its intensity distribution. In this limit, the process transf…
