A duality between a coalescing population model and a noisy long-range FKPP equation, supported by large-scale simulation, shows identical butterfly light cone scaling for alpha>0.5 in 1D.
4(b), we observe an agreement with the numerical data at late times when corrections up to O(ln lnt) are included

Operator Spreading, Duality, and the Noisy Long-Range FKPP Equation
A duality between a coalescing population model and a noisy long-range FKPP equation, supported by large-scale simulation, shows identical butterfly light cone scaling for alpha>0.5 in 1D.
