Modified Character Sums Over the k-Free Integers

Explore a 14-minute mathematics lecture on modified character sums over k-free integers, presented by Caio Cesar Mafia Bueno from UFMG at the 1st Brazilian Workshop in Analytic Number Theory. Learn about recent advances in Number Theory, including developments in analytic and algebraic aspects, as part of a broader initiative to connect Brazilian researchers in the field. Delivered at IMPA (Instituto de Matemática Pura e Aplicada) in Rio de Janeiro, the lecture contributes to a workshop featuring international speakers discussing various topics from Lehmer's problem to partition regularity of squares, aimed at fostering collaboration and establishing networks among number theorists across Brazil.
