Variational Estimates for Nonnegative Harmonic Functions

Jakob Fromherz

Consider a nonnegative harmonic function $u$ on a domain $D \subset R^{d - 1}$ . We establish boundedness of Jones' variational integral on an ultradense, $d - 1$ dimensional sub…

Bounding Radial Variation of positive harmonic Functions on Lipschitz Domains

Jakob Fromherz, Paul F. X. Müller, Katharina Riegler

We provide radial variational estimates for positive harmonic functions on Lipschitz domains in higher dimensions. The intention of this paper is to document an updated and refined…
