Destressing Math Collective with Sarah Lohrey
Sarah Lohrey '25 will give a talk titled "Arithmetic Progressions of Integers that are Relatively Prime to their Digital Sums." Snacks will be served in the Math Lounge starting at 6:30 p.m.
Abstract: A positive integer b ≥ 2 is called b-anti-Niven if it is relatively prime to the sum of the digits in its base-b representation. We explore the maximum lengths of sequences of consecutive b-anti-Niven numbers and arithmetic progressions of b-anti-Niven numbers. This research was done in Summer 2023 as part of the Moravian University Math and Computer Science REU Program.
