Essential concepts for the understanding of the Banach's Theorem, such as metric spaces, sequences and convergence in metric spaces, complete metric spaces, contractions and fixed points of contractions were discussed.restrictedAccessEspaços MétricosMetric SpacesPontos FixosFixed PointsTeorema de BanachBanach's TheorembachelorThesis
