内容記述(抄録等) | Boundedness and asymptotic behavior of solutions and existence of periodic solutions of the scalar generalized logistic equation N^^・(t) = N(t) (a - bN(t - 1) - cN(t - 2)) are discussed. In particular, we show partial global uniform asymptotic stability of the constant solution N (t) = a/(b + c), and existence of nontrivial periodic solutions by using a Hopf bifurcation and a fixed point theorem for a closed convex set.
