Eric Angelini's Greatest Sequences

Neil Sloane, The OEIS Foundation and Rutgers University

Location:  https://rutgers.zoom.us/j/94346444480 [password: The 20th Catalan number, alias (40)!/(20!*21!)
Date & time: Thursday, 19 December 2024 at 5:00PM - 6:00PM

Eric Angelini (1951-2024) was for 20 years one of the most inspired, creative, brilliant contributors to the On-Line Encyclopedia of Integer Sequences (the OEIS). With just a few words ("If a digit d is even, the next digit is greater than d") he could create a sequence that would turn out to be well-defined but often still not fully understood even today. This talk will discuss a few of the 1500 sequences he submitted to the OEIS, such as the Sisyphus sequence, the "Sum and Erase", the 1995 sequence, the "Choix de Bruxelles", the Comma sequence, the Jungfrau, the Triply Fractal, and others as time permits.
