受控梯度流的Hamilton–Jacobi方程:柱形测试函数

Hamilton--Jacobi equations for controlled gradient flows: cylindrical test functions

Giovanni Conforti, Richard C. Kraaij, Daniela Tonon

AI总结:

本文通过引入仅依赖平方度量距离的柱形测试函数,将受控梯度流Hamilton–Jacobi方程的比较原理推广到更光滑的Hamilton量,摆脱了对Tataru距离的依赖,为建立完备存在性理论奠定基础。

摘要:

本文是始于arXiv:2111.13258的研究计划的第二部分,该计划旨在为度量空间中与受控梯度流问题相关的Hamilton–Jacobi方程建立内蕴几何适定性理论。我们的主要贡献在于证明其中已有的比较原理可推出相对于更光滑Hamilton量的粘性解比较原理,这些Hamilton量作用于仅由底层平方度量距离构成的柱形测试函数,其严格定义通过梯度流的演化变分不等式(EVI)表述实现。特别地,新的Hamilton量不再需要使用包含Tataru距离的测试函数。这一实质性简化为进一步发展完备的存在性理论铺平了道路。

英文摘要:

This work is the second part of a program initiated in arXiv:2111.13258 aiming at the development of an intrinsic geometric well-posedness theory for Hamilton-Jacobi equations related to controlled gradient flow problems in metric spaces. Our main contribution is that of showing that the comparison principle proven therein implies a comparison principle for viscosity solutions relative to smoother Hamiltonians, acting on test functions that are mere cylindrical functions of the underling squared metric distance and whose rigorous definition is achieved from the Evolutional Variational Inequality formulation of gradient flows (EVI). In particular, the new Hamiltonians no longer require to work with test functions containing Tataru's distance. This substantial simplification paves the way for the development of a comprehensive existence theory.
