This paper gives the local existence of mild solutions to the Cauchy problem for the complex Ginzburg-Landau type equation $\frac{\partial u}{\partial t} - (λ + i α) Δ u + (κ + i β) {| u |}^{q - 1} u - γ u = 0$ in $ℝ^{N} \times (0, \infty)$ with $L^{p}$ -initial data $u_{0}$ in the subcritical case ( $1 \leq q < 1 + 2 p / N$ ), where $u$ is a complex-valued unknown function, $α$ , $β$ , $γ$ , $κ \in ℝ$ , $λ > 0$ , $p > 1$ , $i = \sqrt{- 1}$ and $N \in ℕ$ . The proof is based on the $L^{p}$ - $L^{q}$ estimates of the linear semigroup ${exp (t (λ + i α) Δ)}$ and usual fixed-point argument.

Suppose that $X$ and $Y$ are Banach spaces and that the Banach space $X {\hat{\otimes}}_{τ} Y$ is their complete tensor product with respect to some tensor product topology $τ$ . A uniformly bounded $X$ -valued function need not be integrable in $X {\hat{\otimes}}_{τ} Y$ with respect to a $Y$ -valued measure, unless, say, $X$ and $Y$ are Hilbert spaces and $τ$ is the Hilbert space tensor product topology, in which case Grothendieck’s theorem may be applied. In this paper, we take an index $1 \leq p < \infty$ and suppose that $X$ and $Y$ are $L^{p}$ -spaces with $τ_{p}$ the associated...

In this paper the notions of uniformly upper and uniformly lower $ℓ$ -estimates for Banach function spaces are introduced. Further, the pair $(X, Y)$ of Banach function spaces is characterized, where $X$ and $Y$ satisfy uniformly a lower $ℓ$ -estimate and uniformly an upper $ℓ$ -estimate, respectively. The integral operator from $X$ into $Y$ of the form $K f (x) = ϕ (x) \int_{0}^{x} k (x, y) f (y) ψ (y) d y$ is studied, where $k$ , $ϕ$ , $ψ$ are prescribed functions under some local integrability conditions, the kernel $k$ is non-negative and is assumed to satisfy certain...
