我们对公式/dt + (γ + iα)κ Σ(u) + (κ + iβ)κ Σ(u) - γu = 0, t>0 ; u(0) =u_0,其中κ Σ和Σ在希尔伯特空间X中的子差异中存在。Let Ω γ R^N是一个边界域。设置X : = L^2(Ω),μ(u) : = (1/p)μ u μ p_<L^p>, u μ W^<1, p>_0(Ω) ; μ(v) : =(1/q)μ v μ q_<L^q>, v μ L^q(Ω),我们有μ(u) =| u(u)|^<q-2>u, u ∈ D(κ ψ) : = L^<2(q-1)>(Ω),κ Σ(u) = -Δ_pu: =-div(|u(|^<p-2> μ u), u μ D(μ) : = {u μ W^<1, p>_0(Ω) ; Δ_pu μ L^2(Ω)}和hence(CGL)_p μ u/μ t - (μ +iα)·Δ_pu+ (μ +iβ)|u(u)|^<q-2>u -\u = 0, t>0 ; u(O) : u_0.Here we have assumed that p [greater than or equal] 2, q [greater than or equal] 2。We have revealed that the global in time solvability of (CGL)_p is classified as follows according to the pair (\/\,\/\)/R^2 and the initial value。在任何情况下,我们都认为|α(α)|/λ [less than or equal] 1/c_p: = 2√<p-1>/(p-2).1.

英文摘要
We have considered initial value problem for abstract evolution equations of the formdu/dt + (λ+ iα)∂φ(u) + (κ + iβ)∂ψ(u) - γu = 0, t>0 ; u(0) =u_0,where ∂φ, ∂ψ are subdifferentials of convex functions φ, ψ on a Hilbert space X.Let Ω ⊂ R^N be a bounded domain. Setting X : = L^2(Ω), φ (u) : = (1/p)‖∇u‖^p_<L^p>, u ∈ W^<1, p>_0(Ω) ; ψ(v) : =(1/q)‖v‖^q_<L^q>, v ∈ L^q(Ω), we have ∂ψ(u) = |u|^<q-2>u, u ∈ D(∂ψ) : = L^<2(q-1)>(Ω), ∂φ(u) = -Δ_pu : =-div(|∇u|^<p-2>∇u), u ∈ D(∂φ) : = {u ∈ W^<1, p>_0(Ω) ; Δ_pu∈ L^2(Ω)} and hence(CGL)_p ∂u/∂t - (λ+iα)・Δ_pu + (κ+iβ)|u|^<q-2>u - γu = 0, t>0 ; u(O) : u_0.Here we have assumed that p 【greater than or equal】 2, q 【greater than or equal】 2. We have revealed that the global in time solvability of (CGL)_p is classified as follows according to the pair (α/λ, β/κ) ∈ R^2 and the initial value. In any case we assume that |α|/λ 【less than or equal】 1/c_p : = 2√<p-1>/(p-2).1. Existence of weak solutions for any (α/λ, β/κ), u_0 ∈ L^2(Ω)(no uniqueness, in general)2. Existence of strong solutions for (α/λ, β/κ) belonging to "(CGL) region" : = {(x, y) ∈ R^2 ; xy 【greater than or equal】 0 or |xy| - 1 < (|x| + |y|)/c_q} and u_0 ∈ W^<1, p>_0(Ω) ∩ L^q(Ω) (no uniqueness, in general)3. Unique existence of strong solutions for (α/λ, β/κ) with |β|/κ 【less than or equal】 1/c_q and u_0 ∈ L^2(Ω) (smoothing effect of solution operators).
