Title: An algebraic treatment of congruences in Number Theory.
Speaker: Konstantinos Smpokos
Date and Time: Friday, October 6 , 1:00-2:00pm
Place: Rome 206
Abstract: In this talk I will present a research paper that has been published in the Bulletin of the Hellenic mathematical society in December 2016.We will discuss the behavior of certain free abelian subgroups of the multiplicative group of positive rationals and their relationship with the group of units of integers modulo n.The methods we will use are purely algebraic.
