Regular potentials of additive functionals in semidynamical systems

Nedra Belhaj Rhouma, Mounir Bezzarga (2004)

Commentationes Mathematicae Universitatis Carolinae

We consider a semidynamical system ( X , , Φ , w ) . We introduce the cone 𝔸 of continuous additive functionals defined on X and the cone 𝒫 of regular potentials. We define an order relation “ ” on 𝔸 and a specific order “ ” on 𝒫 . We will investigate the properties of 𝔸 and 𝒫 and we will establish the relationship between the two cones.

Regularity of some nonlinear quantities on superharmonic functions in local Herz-type Hardy spaces.

Dashan Fan, Shanzhen Lu, Dachun Yang (1998)

Publicacions Matemàtiques

In this paper, the authors introduce a kind of local Hardy spaces in Rn associated with the local Herz spaces. Then the authors investigate the regularity in these local Hardy spaces of some nonlinear quantities on superharmonic functions on R2. The main results of the authors extend the corresponding results of Evans and Müller in a recent paper.

Remarks on pluripolar hulls

Le Mau Hai, Nguyen Quang Dieu, Tang Van Long (2004)

Annales Polonici Mathematici

The aim of the paper is to establish some results on pluripolar hulls and to define pluripolar hulls of certain graphs.

Remarks on subharmonic envelopes.

Duong Ngoc Son (2006)

Publicacions Matemàtiques

We prove that the subharmonic envelope of a lower semicontinuous function on Omega is harmonic on a certain open subset of Omega, using a very classical method in potential theory. The result gives simple proofs of theorems on harmonic measures and Jensen measures obtained by Cole and Ransford.
