Stochastic travelling wave solution of the $ N $-species cooperative systems with multiplicative noise

  • Received: 09 March 2023 Revised: 28 April 2023 Accepted: 21 May 2023 Published: 12 June 2023
  • The current paper is devoted to the stochastic $ N $-species cooperative system with a moderately strong noise. By the theory of monotone random systems and the technique of suitable marker of wavefront, the existence of the travelling wave solution is established. By applying the Feynman-Kac formula and sup-sub solution technique, the upper and lower bounded of the asymptotic wave speed are also obtained. Finally, we give an example for stochastic 3-species cooperative systems.
