EN By using the fixed point method, we investigate the generalized Hyers-Ulam stability of group homomorphisms and ring homomorphisms. Our work brings some complements and some continuations to the results obtained previously by R. Badora (On approximate ring homomorphisms published in J. Math. Anal. Appl, 276, (2002), 589-597) and those of D. Zhang and H-X. Cao (Stability of group and ring homomorphisms, Mathematical Inequalities & Applications, 9(3)(2006), 521-528).
