Four fermion final states in $e^{+}{e}^{-}$ annihilation

Abstract

The present status of calculations of four fermion final states is reviewed. Higher order problems arising there are pointed out. Special attention is paid to results obtained in the semi-analytical approach and their limitations and perspectives.
