Uniform approximation by harmonic functions on compact subsets of $\mathbb R^3$
M. Ya. Mazalov Military Academy of Air Defence Forces of Russia Federation named after A. M. Vasilevskii, Smolensk, Russia
Abstract:
We consider uniform approximation by harmonic functions on compact subsets in $\mathbb R^3$. Under an additional assumption that an approximated function is Dini-continuous, we prove a natural analog of Vitushkin's well-known uniform approximation lemma for an individual analytic function.
Key words and phrases:
uniform approximation, harmonic function, capacity, Virtushkin scheme.
