• TITLE: Some Theorems for Real Increasing Functions in Elementary Fixed Point Theory

  AUTHORS: Maria Luigia Diviccaro, Salvatore Sessa

  KEYWORDS: Increasing Function, Upper Broad Sequentially Semicontinuity on the Right, Greatest Fixed Point

  ABSTRACT: We obtain some theorems for real increasing functions showing that elementary fixed point theory can bring to astonishing results by assuming only a few properties, some of which intrinsically possessed from these functions. An application is given for a theorem of quasi-compactness and a known result in posets is also recalled and applied to real intervals.
