A fixed point theorem is proved in a Banach spaceEwhich has uniformly normal structure for asymptotically regular mappingTsatisfying: for eachx,yin the domain and forn=1,2,⋯,‖Tnx−Tny‖≤an‖x−y‖+bn(‖x−Tnx‖+‖y−Tny‖)+cn(‖x−Tny‖+‖y−Tny‖),wherean,bn,cnare nonnegative constants satisfying certain conditions. This result generalizes a fixed point theorem of Górnicki [1].
