Liu, Zeqing On Ćirić type mappings with a nonunique coincidence points. (English) Zbl 0832.54035 Mathematica 35(58), No. 2, 221-225 (1993). The author shows that two results of J. Achari [ibid. 22(45), 5-8 (1980; Zbl 0465.54035)] are false and gives corrected versions in Section 2. Coincidence point theorems of Ćirić type [Publ. Inst. Math., Nouv. Sér. 17(31), 52-58 (1974; Zbl 0309.54035)] are given for three selfmaps of a metric space using the weak commutativity concept due to the reviewer [ibid. 32(46), 149-153 (1982; Zbl 0523.54030)].
