On December 4, 2025, at 14:00 EET, Mihai Prunescu (University of Bucharest & IMAR) will give a talk in the Logic Seminar.
Title: Elementary closed forms for non-trivial divisors
Abstract:
Some arithmetic terms t have the property that, for every composite natural number n, the value t(n) is a proper non-trivial divisor of n. This is joint work with Joseph M. Shunia.
