Streszczenie
The purpose of this paper is to present several fixed point theorems for the so-called set-valued $Y$-contractions. Set-valued $Y$-contractions in ordered metric spaces, set-valued graphic contractions, set-valued contractions outside a bounded set and set-valued operators on a metric space with cyclic representations are considered.
