Feynman-Kac Representation and the Asymptotic Speed of the Fisher-KPP Equation with Finite-Activity Jump Noise

Yuhong Li, Hao Wen, Jianhua Huang

We study the asymptotic propagation speed of travelling wave solutions to the stochastic Fisher--KPP equation with multiplicative finite-activity pure jump Lévy noise, i.e.\ a comp…
