• Description:
  The Bolzano-Weierstrass principle of choice is the oldest method of the set theory, traditionally used in mathematical analysis. We are extending it towards transfinite sequences of steps indexed by ordinals. We are introducing the notions: hiker's tracks, hiker's maps and principles Pn(X,Y,m); which are used similarly in finite, countable and uncountable cases. New proofs of Ramsey's theorem and Erdős-Rado theorem are presented as some applications
