| contents | We consider the existence and uniqueness of a minimizer of the extremal problem for weighted combined energy between two concentric annuli and obtain that the extremal mapping is a certain radial mapping. Meanwhile, this in turn implies a Nitsche type phenomenon and we get a $\frac{1}{|w|^λ}-$Nitsche type inequality ($λ\neq1$). As an application, on the basis of the relationship between weighted combined energy and weighted combined distortion, we also investigate the extremal problem for weighted combined distortion on annuli. This extends the result obtained by Kalaj in \cite{Ka1}. |
