Yoshida, Kiyoshi; Kishimoto, Kazuo Effect of two time delays on partially functional differential equations. (English) Zbl 0572.35086 Kumamoto J. Sci., Math. 15, 91-109 (1983). The authors study the Hutchinson equation with diffusion and two time delays in a bounded domain with no-flux boundary conditions. The existence of a stable, spatially inhomogeneous periodic solution is proved using Hopf bifurcation techniques. The space dependence of such solution is a novel feature with respect to the analogous one-delay model investigated in K. Yoshida [Hiroshima Math. J. 12, 321-348 (1982; Zbl 0522.35011)].
