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.
