Abstract:
A beautiful example of a global property being determined by a local one is the Morse-Hedlund Theorem; it gives the relation between the global property of periodicity for an infinite word in a finite alphabet and local information on the complexity of the word. This simple relation quickly leads to numerous generalizations and many open problems.Date: Friday, May 15, 2015
