Cauchy-Lipschitz定理的两个空间推广

A two spaces extension of Cauchy-Lipschitz Theorem

Charles Bertucci, Pierre Louis Lions

AI总结:

本文将Cauchy-Lipschitz理论推广到可用两个范数量化非线性项的情形,分别建立常微分方程与偏微分方程的局部适定性结果。

摘要:

我们将演化问题局部适定性的经典理论调整到非线性项可由两个不同范数精确量化的情形。对于常微分方程,我们考虑方程$\dot{x}=f(x,x)$,其中函数$f:V\times E\to E$,$E$是Banach空间,而$V\hookrightarrow E$是赋范向量空间。该结构使我们能够区分$f$对$x$的两种依赖关系,并可推广经典结果。我们还证明了偏微分方程的类似结果。

英文摘要:

We adapt the classical theory of local well-posedness of evolution problems to cases in which the nonlinearity can be accurately quantified by two different norms. For ordinary differential equations, we consider $\dot{x} = f(x,x)$ for a function $f: V\times E \to E$ where $E$ is a Banach space and $V \hookrightarrow E$ a normed vector space. This structure allows us to distinguish between the two dependencies of $f$ in $x$ and allows to generalize classical results. We also prove a similar results for partial differential equations.
