Title: Where is the spiral?
Abstract: It is a known fact that the partial sums of some trigonometric series generate appealing patterns when plotted as points in the complex plane. The usual explanation is based on variants of the stationary phase approximation employed in analytic number theory. In a simple case, the theory predicts an Archimedean spiral, but the computer shows a very different experimental truth. It turns out that at least for integer values of a parameter the computer plot can be explained solving a curious recurrence relation.

Spring 2020 Semester

Date: Thurs., Jan. 30, 2020

Speaker: Doron Zeilberger, Rutgers University

Title: 0, 1, 8, 78, 944, 13800, 237432, 4708144, 105822432, 2660215680, 73983185000, 2255828154624, ...: "The sequence that started it all"

Abstract: OEIS sequence A1 (that starts: 0, 1, 1, 1, 2, 1, 2, 1, 5, 2, 2, 1, 5, 1, 2, 1, 14, 1, 5, 1, 5, 2, 2, 1, 15, 2, 2, 5, 4, 1, 4 ...) is not the chronologically first sequence in the amazing On-Line Encyclopedia of Integer Sequences. This honor goes to OEIS sequence A435, that according to Neil Sloane was the "sequence that started it all". In addition to its immense historical significance it is very interesting mathematically, and leads to new sequences. [Joint work with Yukun Yao]
