Generating Flows on Metric Spaces

✍ Craig Calcaterra; David Bleecker 📂 Article 📅 2000 🏛 Elsevier Science 🌐 English ⚖ 212 KB

The notion of an arc field on a locally complete but not necessarily locally . compact metric space is introduced as a generalization of a vector field on a manifold. Generalizing the Cauchy᎐Lipschitz Theorem, sufficient conditions on arc fields are given under which the existence and uniqueness of

Nonlinear balayage on metric spaces

✍ Anders Björn; Jana Björn; Tero Mäkäläinen; Mikko Parviainen 📂 Article 📅 2009 🏛 Elsevier Science 🌐 English ⚖ 1019 KB

We develop a theory of balayage on complete doubling metric measure spaces supporting a Poincaré inequality. In particular, we are interested in continuity and p-harmonicity of the balayage. We also study connections to the obstacle problem. As applications, we characterize regular boundary points a
