The authors proves some fixed point theorems for families of weakly nonexpansive maps under some relatively weaker and more general conditions. These results generalize and improve several results due to Jungck (2001; Zbl 1005.47052), Jachymski (1993; Zbl 0795.54054), Guo (1993; Zbl 0796.54045), Rhoades (1977; Zbl 0365.54023), and others.
