英文摘要:

      In this paper, we obtain several fixed point theorems for orbitally contractions and quasicontractions in a space (X,d,ρ) with two metrics d and ρ, and extend some main results of [1-9].In the next place, we obtain a common fixed point theorem for commuting selfmappings of the space (X,d,ρ). It unify and generalize some main results of [12-15].
