有界Lipschitz域上SPDE的Lp-理论[5]设p ∈ [2,∞),θ ∈ d + p− 2.设f ∈ Lp(ΩT ;H γ−2 p,θ+p(O))&(g k)∈ Lp(ΩT ;H γ−1 p,θ(O; l2))& u0 ∈ Lp(Ω;H γ−2/p p,θ+p−2(O))。然后,在对系数aij和σik适当的抛物性和光滑性假设下,存在唯一的随机过程u ∈ Lp(ΩT ;H γ p,θ−p(O)),使得对所有φ ∈ C∞ 0(O),P-几乎必然对所有t ∈ [0,T ]:
Spatial Besov regularity of SPDEs An Lp-theory for SPDEs on bounded Lipschitz domains [5] Let p ∈ [2,∞) and θ ≈ d + p− 2. Assume that f ∈ Lp(ΩT ;H γ−2 p,θ+p(O)) & (g k) ∈ Lp(ΩT ;H γ−1 p,θ (O; l2)) & u0 ∈ Lp(Ω;H γ−2/p p,θ+p−2(O)). Then, under suitable parabolicity and smoothness assumptions on the coefficients aij and σik, there exists a unique stochastic process u ∈ Lp(ΩT ;H γ p,θ−p(O)), such that for all φ ∈ C∞ 0 (O), P-almost surely for all t ∈ [0, T ]:
