Krein-Feller operators on Riemannian manifolds: compactness of embedding and Hodge's theorem

Sze-Man Ngai, Lei Ouyang

For a bounded open set Omega in a complete oriented Riemannian n-manifold and a positive finite Borel measure mu with support contained in Omega, we define an associated Krein-Fell…

Iterated relation systems on Riemannian manifolds

Jie Liu, Sze-Man Ngai, Lei Ouyang

For fractals on Riemannian manifolds, the theory of iterated function systems often does not apply well directly, as fractal sets are often defined by relations that are multivalue…

Differential equations defined by Kre\uÄ±n-Feller operators on Riemannian manifolds

Sze-Man Ngai, Lei Ouyang

We study linear and semi-linear wave, heat, and SchrÃ¶dinger equations defined by Kre\uÄ±n-Feller operator $- I^_{I^} ¼$ on a complete Riemannian $n$ -manifolds $M$ , where $I^¼$ is a fini…
