Abstract:
In this paper we study some boundary properties of harmonic functions defined in the unit disk in dependence of the location of $P'$-sequences on chords and horocycles. We introduce notions of $P'$-chords, normal chords, $P'$-horocycles, and normal horocycles.
Keywords:harmonic functions, non-Euclidean circles, radii and distances, $P'$-sequence, $P'$-chord, horocyclic point, horocyclic angle.
