Filters and limits in filtered spaces

  • David Carf`ı Department of Mathematics, University of California Riverside

Abstract

In this lecture  notes,  we study filters and limits in a feasible  sufficiently general  way for  many  applications  to  Physics,  Economics and  Social  Science.    In particular  we analyze:



  • Filters;



  • Filter bases;



  • Basic example in topological  spaces;



  • Basic examples in preordered spaces;



  • Filtered spaces;



  • Induced filter bases;



  • Examples in topological spaces;



  • Examples on the real line;



  • Limits;



  • Limits with respect to filter bases;



  • Limits with respect to filter bases  on subspaces;



  • Limits and topology;



  • Limits of functions on topological  spaces;



  • Limits of functions on a topological  subspace;



  • Some basic theorems for topology;



  • Unicity of the limit in Hausdor spaces;



  • Limits and functionals;



  • Limits for real functional;



  • Limits and operations;



  • Local boundness;



  • Complements;



  • Limits and convergence of filtered bases;



  • Limit of composition.
