This first quantity is worried with the analytic derivation of particular formulation for the leading-order Taylor approximations of (local) stochastic invariant manifolds linked to a wide type of nonlinear stochastic partial differential equations. those approximations take the shape of Lyapunov-Perron integrals, that are extra characterised in quantity II as pullback limits linked to a few partly coupled backward-forward platforms. This pullback characterization presents an invaluable interpretation of the corresponding approximating manifolds and results in an easy framework that unifies another approximation techniques within the literature. A self-contained survey can be incorporated at the lifestyles and charm of one-parameter households of stochastic invariant manifolds, from the viewpoint of the speculation of random dynamical systems.

For instance, the Lipschitz condition on the nonlinearity can be replaced by certain dissipative conditions on the nonlinear terms which hold for a broad class of physical problems. We refer again to the aforementioned works [33, 92, 138, 143, 147] for more details; see also [37, 58, 76, 85]. A direct consequence of this proposition is that, for any λ and any (F ; B(Hα ))measurable random initial datum v0 (ω), there exists a unique classical solution vλ,v0 (ω) (t, ω) := vλ (t, ω; v0 (ω)) of Eq.

1). 2 hold with r specified therein. 13) is a global stochastic invariant C r -manifold of Sλ . 3 below. As explained in Chap. 2, the corresponding results may be viewed as complementary to previous results obtained on the topic [12, 42, 51, 57, 142, 144, 155]. Furthermore, some new insights concerning the asymptotic completeness problem are provided. 1] that we adapt to our framework; see also [42]. More precisely, for a given solution u λ to Eq. 1) we look for a solution u λ living on the random invariant manifold Mλ such that u λ (t, ω) − u λ (t, ω) α decays exponentially as t → ∞ for almost all ω.

36) Step 4. 28). We show in this step that for each ω ∈ Ω there exists q ∈ Hαs such that the constraint u 0 (ω) := vλ [q](0, ω) + u 0 (ω) ∈ Mλ (ω) is satisfied. 2 Asymptotic Completeness of Stochastic Invariant Manifolds q = Psvλ [q](0, ω). 37) Note also that an initial datum u 0 (ω) given by vλ [q](0, ω)+u 0 (ω) belongs to Mλ (ω) if u 0 (ω) = p + h λ ( p, ω) for some p ∈ H c, where h λ is the random invariant manifold function of Eq. 1. Since q = Psvλ [q](0, ω), it is thus natural to seek for q of the following form: q = Psvλ [q](0, ω) = Ps(u 0 (ω) − u 0 (ω)) = h λ ( p, ω) − Psu 0 (ω).
