DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/13/">Ho
 tspot Lemmas for Noncompact Spaces</a>\nby Bill Mance (Adam Mickiewicz Uni
 versity in Poznań) as part of One World Numeration seminar\n\n\nAbstract\
 nWe will explore a correction of several previously claimed generalization
 s of the classical hotspot lemma. Specifically\, there is a common mistake
  that has been repeated in proofs going back more than 50 years. Corrected
  versions of these theorems are increasingly important as there has been m
 ore work in recent years focused on studying various generalizations of th
 e concept of a normal number to numeration systems with infinite digit set
 s (for example\, various continued fraction expansions\, the Lüroth serie
 s expansion and its generalizations\, and so on). Also\, highlighting this
  (elementary) mistake may be helpful for those looking to study these nume
 ration systems further and wishing to avoid some common pitfalls.\n
