摘要
We present a short proof of the following natural extension of Wright's famous 3/2-stability theorem: the conditions tau <= 3/2, c >= 2 imply the presence of the positive traveling fronts (not necessarily monotone) u = phi(x . nu + ct), vertical bar nu vertical bar = 1, in the delayed KPP-Fisher equation u(t)(t, x) = Delta u(t, x) + u(t, x)(1 - u(t - tau, x)), u >= 0, x is an element of R-m.
