Abstract (2. Language):
Using the properties of planar quasiconformal mappings, we obtain the solutions
for the Grötzsch extremal problem on the annulus. We also point out the shortcoming used
in [3] for solving this extremal problem. Moreover, by the hyperbolic area distortion and the
property of domain module, one criterion for the solution of the Grötzsch annulus extremal
problem is given under some conditions.
