SUMMARY:Pure Math Grad Colloquium
CLASS:PUBLIC
DESCRIPTION:JON CHEAH\, UNIVERSITY OF HONG KONG\n\n_An advertisement of clu
 ster algebras_\n\nCluster algebras have had many surprising links with man
 y areas of\nmathematics beyond their original purpose in studying total\np
 ositivity. In this expository talk\, we consider two discrete\ndynamical s
 ystems\, namely Markov triples and Coxeter--Conway friezes.\nWhile the stu
 dy of these examples predated that of cluster theory\, we\nwill see how th
 e latter provides a conceptual explanation for the\nintergrality and posit
 ivity phenomena.\n\nMC 5479\n\n(snacks at 16:00)
