Prof. Michael Saclolo will discuss how a poetic form has influenced modern mathematics.  This form, the sestina, dates to the Middle Ages.  The earliest known sestina is by a troubadour named Arnaut Daniel.  The sestina features a permutation of six, as reflected in its stanza’s ending words. Permutations have long been a topic of study among mathematicians.  Arnaut’s sestina led to a mathematical question about permutations whose full resolution was not realized until this century.  This presentation will chronicle the development of this question, providing a glimpse of how literature and mathematics can connect.  Please RSVP below.
