Title of Lecture: Poincare and Perron; 100+ years later

Time and Place: SR 207, Thursday, November 29 at 3:30 pm; Reception: SR 318 at 3:00 pm

Abstract: More than 100 years ago, Poincare and Perron initiated the study of the asymptotic behavior of solutions of linear recurrence relations in several ground-breaking papers. After explaining these classical results, the focus of the talk is to consider several questions that were left open and how more recent work has lead to answers which now give us a more complete asymptotic theory. Finally, the theory will be applied to some special cases which were originally treated using more ad hoc techniques.
