用确定性对策求解次黎曼群中的奇异发展问题

Solving singular evolution problems in sub-Riemannian groups via deterministic games

Pablo Ochoa, Julio Alejo Ruiz

摘要:

本文证明了奇异抛物型方程在Carnot群上的黏性解的存在性。我们通过构建适合卡诺群的代数和微分结构的适当的确定性游戏来发展分析。我们指出,存在性的证明不需要比较,它是基于一个Arzela-Ascoli型定理。

英文摘要:

In this manuscript, we prove existence of viscosity solutions to singular parabolic equations in Carnot groups. We develop the analysis by constructing appropriate deterministic games adapted to the algebraic and differential structures of Carnot groups. We point out that the proof of existence does not require comparison and it is based on an Arzela-Ascoli-type theorem.
