Existence of random best approximation for noncommutative maps (Q928538)

Some results on common random fixed point from the set of random best approximations are proved for noncommutative random maps. In Theorem 6, the author utilizes the concept of ``R-subcommutative weakly random operator'' without defining it. Reviewer's remark: There is no need to present the results which were already proved in more compact and correct form (e.g., Theorem 6 was reported in [\textit{I. Beg} and \textit{N. Shahzad}, Arch. Math. 74, No. 4, 298--301 (2000; Zbl 0956.47023)]).
