Abstract:
New uniform approximability criteria formulated in terms of logarithmic capacity are obtained for approximations by harmonic functions on compact sets in $\mathbb R^2$. A relationship between these approximations and analogous approximations on compact sets in $\mathbb R^3$ is established.
Keywords:
uniform approximation by harmonic functions, Vitushkin-type localization operator, harmonic capacity, logarithmic capacity, reduction method.
