I'm trying to compute the Higgs to gluon pair decay at 1-loop using Feyncalc and FeynHelper (to connect with Package-X). I first define variables and loop part as: ... [feyncalc]

Note: This question is for those chaotic systems where the order of maximal Lyapunov exponent is around $10^{-3}$. So it's different from normal chaotic systems like HénonHeiles system, Yang-Mills-... [plotting] [conditional] [code-review] [head]

Score of 3 Riesz fractional derivatives/Laplacian for Lévy flights? https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=299809
There are pretty popular Lévy flights for diffusion with steps of infinite variance, mathematically requiring Riesz fractional derivatives, which in Fourier transform multiplies by $|k|^\alpha$. I ... [differential-equations] [random-process] [fractional-calculus]
