Willem-Jan Pannekoek,Johannes L. Bosthe Möbius transformation .. A lift of an element α ∈ PSL (2, ℂ) is an element A ∈ SL (2, ℂ) with P (A) = α, while a lift of a subgroup . of PSL(2, ℂ) is an isomorphism . SL(2, ℂ) such that P . is the identity.

Ce n’était pas le premier travail de l’auteur, qui avait fait auparavant un PhD intitulé «Generalizations of some classical theorems to the case of functions of several variables» sous la direction de Salomon Bochner (Princeton 1947).

H. E. Rauch, Function Theorist,and [10] with M. Gerstenhaber propose a forward-looking method for using the then undeveloped theory of harmonic maps to prove Teichmüller’s theorem about extremal quasi-conformal maps. His 1979 paper [14] with L. Keen and A. T. Vasquez sheds interesting light on the accessory parameter problem in t

After the works of a number of mathematicians, W. C. Graustein took up the real case in 1924-, without completely settling the problem. An authoritative study of this problem was carried out by Elie Carta

Such foliations . will turn out to be either flat or homogeneous. As a global application we obtain that the Hopf fibrations S. → ℂ .. are the only metric fibration
