The Nitsche conjecture
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
The conjecture in question concerns the existence of a harmonic homeomorphism between circular annuli A(r,R) and A(r*,R*), and is motivated in part by the existence problem for dou…

Harmonic mappings of an annulus, Nitsche conjecture and its generalizations
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
As long ago as 1962 Nitsche conjectured that a harmonic homeomorphism between planar annuli exists if and only if $\frac{R_*}{r_*} \ge {1/2} (\fra…
