Analysis of Velocity Fluctuation in Turbulence based on Generalized Statistics
T. Arimitsu, N. Arimitsu
The numerical experiments of turbulence conducted by Gotoh et al. are analyzed precisely with the help of the formulae for the scaling exponents of velocity structure function and…
PDF of Velocity Fluctuation in Turbulence by a Statistics based on Generalized Entropy
Toshihico Arimitsu, Naoko Arimitsu
An analytical formula for the probability density function (PDF) of the velocity fluctuation in fully-developed turbulence is derived, non-perturbatively, by assuming that its unde…
Positivity constraints on photon structure functions
K. Sasaki, J. Soffer, T. Uematsu
We investigate the positivity constraints for the structure functions of both virtual and real photon. From the Cauchy-Schwarz inequality we derive three positivity conditions for…
Multifractal Analysis of Turbulence by Statistics based on Non-Extensive Tsallis' or Extensive Rényi's Entropy
N. Arimitsu, T. Arimitsu
An analytical expression of probability density function (PDF) of velocity fluctuation is derived with the help of the statistics based on generalized entropy (the Tsallis entropy…
A Characterization of Discrete Time Soliton Equations
Satoru Saito, Noriko Saitoh, Jun-ichi Yamamoto +1
We propose a method to characterize discrete time evolution equations, which generalize discrete time soliton equations, including the -difference Painlevé IV equations discusse…
Zee model and phenomenology of lepton sector
Eiichi Mitsuda, Ken Sasaki
The virtual effects of the Zee charged scalar boson on the lepton-family-number (LFN) violating processes are studied. We obtain the constraints on the individual Yukawa coupling c…
