In this paper, we investigate the following non-local Cauchy problem of nonlinear population evolution equation with random periodic migration perturbation,{(p(r,t))/(t)+(p(r,t))/(r)=-μ(r)p(r,t)+f(t,p(r,t)),0<r<rm,t0p(r,0)=p0(r)+g(p(r,t0)),T>t0>0 p(0,t)=β(t)integral from n=r1 to r2 k(r)h(r)p(r,t)dr, t≥0.
研究如下形式具有随机周期移民扰动的非线性种群发展方程的非局部柯西问题,{(p(r,t))/(t)+(p(r,t))/(r)=-μ(r)p(r,t)+f(t,p(r,t)),0t0>0 p(0,t)=β(t)integral from n=r1 to r2 k(r)h(r)p(r,t)dr这里,其他地区的种群迁入项f以及非局部条件项g为紧算子,且f是时间变量t的周期为T的周期函数。
