Universal fluctuations and extreme value statistics
Kajsa Dahlstedt, Henrik Jeldtoft Jensen
Abstract
We study the effect of long range algebraic correlations on extreme value statistics and demonstrate that correlations can produce a limit distribution which is indistinguishable from the ubiquitous Bramwell-Holdsworth-Pinton distribution. We also consider the square-width fluctuations of the avalanche signal. We find, as recently predicted by T. Antal, M. Droz G. Gyorgyi and Z. Racz for logarithmic correlated 1/f signals, that these fluctuations follow the Fisher-Tippett-Gumbel distribution from uncorrelated extreme value statistics.
