• The Radó-Kneser-Choquet theorem for p-harmonic mappings between Riemannian surfaces 

  Adamowicz, Tomasz; Jääskeläinen, Jarmo; Koski, Aleksis (European Mathematical Society Publishing House, 2020)

  In the planar setting, the Radó–Kneser–Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. ...

• Notions of Dirichlet problem for functions of least gradient in metric measure spaces 

  Korte, Riikka; Lahti, Panu; Li, Xining; Shanmugalingam, Nageswari (European Mathematical Society Publishing House, 2019)

  We study two notions of Dirichlet problem associated with BV energy minimizers (also called functions of least gradient) in bounded domains in metric measure spaces whose measure is doubling and supports a (1, 1)-Poincaré ...

• Existence and almost uniqueness for p-harmonic Green functions on bounded domains in metric spaces 

  Björn, Anders; Björn, Jana; Lehrbäck, Juha (Elsevier, 2020)

  We study (p-harmonic) singular functions, defined by means of upper gradients, in bounded domains in metric measure spaces. It is shown that singular functions exist if and only if the complement of the domain has positive ...
