• The annular decay property and capacity estimates for thin annuli 

  Björn, Anders; Björn, Jana; Lehrbäck, Juha (Springer Italia Srl; Universitat de Barcelona, 2017)

• Sharp capacity estimates for annuli in weighted R^n and in metric spaces 

  Björn, Anders; Björn, Jana; Lehrbäck, Juha (Springer Berlin Heidelberg, 2017)

  We obtain estimates for the nonlinear variational capacity of annuli in weighted Rn and in metric spaces. We introduce four different (pointwise) exponent sets, show that they all play fundamental roles for capacity ...

• A nontraditional approach for solving the Neumann problem by the finite element method 

  Křižek, Michal; Neittaanmäki, Pekka; Vondrák, Miroslav (Sociedade Brasileira de Matemática Aplicada e Computacional, 1992)

  We present a new variational formulation of a second order order elliptic problem with the Neumann boundary conditions. This formulation does not require any quotient spaces and is advisable for finite element approximations.

• 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 ...

• Admissibility versus Ap-Conditions on Regular Trees 

  Nguyen, Khanh Ngoc; Wang, Zhuang (De Gruyter, 2020)

  We show that the combination of doubling and (1, p)-Poincaré inequality is equivalent to a version of the Ap-condition on rooted K-ary trees.
