Local invariant manifolds for delay differential equations with state space in C1((−∞, 0], R n)
Consider the delay differential equation x 0 (t) = f(xt) with the history xt : (−∞, 0] → Rn of x at ‘time’ t defined by xt(s) = x(t + s). In order not to lose any possible entire solution of any example we work in the Fréchet space C 1 ((−∞, 0], Rn with the topology of uniform convergence of maps an...

| 520 | 3 | |a Consider the delay differential equation x 0 (t) = f(xt) with the history xt : (−∞, 0] → Rn of x at ‘time’ t defined by xt(s) = x(t + s). In order not to lose any possible entire solution of any example we work in the Fréchet space C 1 ((−∞, 0], Rn with the topology of uniform convergence of maps and their derivatives on compact sets. A previously obtained result, designed for the application to examples with unbounded state-dependent delay, says that for maps f which are slightly better than continuously differentiable the delay differential equation defines a continuous semiflow on a continuously differentiable submanifold X ⊂ C 1 of codimension n, with all time-t-maps continuously differentiable. Here continuously differentiable for maps in Fréchet spaces is understood in the sense of Michal and Bastiani. It implies that f is of locally bounded delay in a certain sense. Using this property – and a related further mild smoothness hypothesis on f – we construct stable, unstable, and center manifolds of the semiflow at stationary points, by means of transversality and embeddings. | |
