abstract = {In this paper, I prove the existence and uniqueness of fixed points in complete extended    b-metric spaces for Kannan and Chatterjea contractions in a single-valued setting. We also prove the existence of fixed points in complete extended    b-metric spaces for the existence of fixed points in complete extended    b-metric spaces for Nadler and Kannan-type contractions in a multi-valued setting.}
