Modeling the emergence of modular leadership hierarchy during the collective motion of herds made of harems
Katalin Ozogány, Tamás Vicsek
Gregarious animals need to make collective decisions in order to keep their cohesiveness. Several species of them live in multilevel societies, and form herds composed of smaller c…
Distribution of Maximal Luminosity of Galaxies in the Sloan Digital Sky Survey
M. Taghizadeh-Popp, K. Ozogany, Z. Racz +2
Extreme value statistics (EVS) is applied to the distribution of galaxy luminosities in the Sloan Digital Sky Survey (SDSS). We analyze the DR8 Main Galaxy Sample (MGS), as well as…
Order statistics of 1/f^α signals
N. R. Moloney, K. Ozogany, Z. Racz
Order statistics of periodic, Gaussian noise with 1/f^α power spectrum is investigated. Using simulations and phenomenological arguments, we find three scaling regimes for the aver…
Renormalization group theory for finite-size scaling in extreme statistics
G. Gyorgyi, N. R. Moloney, K. Ozogany +2
We present a renormalization group (RG) approach to explain universal features of extreme statistics, applied here to independent, identically distributed variables. The outlines o…
Finite-size scaling in extreme statistics
G. Gyorgyi, N. R. Moloney, K. Ozogany +1
We study the convergence and shape correction to the limit distributions of extreme values due to the finite size (FS) of data sets. A renormalization method is introduced for the…
Maximal height statistics for 1/f^alpha signals
G. Gyorgyi, N. R. Moloney, K. Ozogany +1
Numerical and analytical results are presented for the maximal relative height distribution of stationary periodic Gaussian signals (one dimensional interfaces) displaying a 1/f^al…
