Exploring polynomial equations through Field Theory
 
 
Description: 

In this talk, we explore the intricate connections between polynomial equations, field theory, and the fascinating realm of roots of unity. Drawing on recent research advancements, we will present compelling examples that illustrate the significance of our collaborative work with Kenneth Ward, Mpendulo Cele, Elizabeth Mrema, Chad Brache Valentijn Karemaker, and Jeroen Sijsling. Together, we have explored intriguing concepts such as radical closure, Artin-Schreier closure, and elementary closure, with a particular focus on the roots of unity.

Through our discussions, we will shed light on the profound connections between polynomials, field theory, and roots of unity, revealing their intrinsic relationship and their impact on modern mathematical research. By the end of the talk, participants will gain new insights into the rich tapestry of these concepts and discover exciting research directions that lie ahead.
