In this paper, we first consider Nadler type contractions with the
generalized Lipschitz constant k holding r(k)<1 instead of r(sk)<1
where r(k) is the spectral radius of k and s≥1 is the coefficient
of the underlying cone b-metric spaces over Banach algebras. Then, we
prove the corresponding fixed point theorem for such mappings. Finally, we
compare our result with one obtained by the case r(sk)<1 by introducing
some proper examples.
