On the localization of the poles of the best Mobius approximations of f
Hugo Arbelaez, Martin Chuaqui, Rodrigo Hernandez +1
We study the localization of the poles of the best Mobius approximations for locally univalent functions in the unit disk. Sharp geometric bounds for the pole function are establis…
