Conformally-projectiv harmonic mappings of equidistant spaces
This paper is dedicated to compositions of conformal and geodesic mappings, which are at the same time harmonic (conformally-projective harmonic). We show relations between conformally-projective harmonic mappings and equid...

On lattice structure of the space of pointwise limits of harmonic functions
It is shown that the space of all pointwise limits of harmonic functions on an open set $U$ is a lattice in the natural ordering if and only if the set of all regular points of $U$ is an $F_sigma$--set....

On Baire and Harmonic Functions
Let us consider two spaces of harmonic functions. First, the space H(U) of functions harmonic on a bounded open subset U of Rn and continuous to the boundary. Second, the space H0(K) of functions on a comp...
