Abstract.   In this paper a J. C. C. Nitsche type inequality for polyharmonic mappings between rounded annuli on the Euclidean space R^d is considered. The case of radial biharmonic mappings between annuli on the complex plane and the corresponding inequality is studied in detail.

2010 Mathematics Subject Classification.   30C55, 31C05.

Key words and phrases.   Harmonic mappings, poly-harmonic mappings, annuli.
