Fundamental theorems from group theory

Other Conferences, 2022
Modern algebra is importance for advanced math. It includes group theory, ring theory, and field theory. For the first course of Modern algebra, group theory, is not easy to think. Furthermore, group theorem is also a study of algebraic structure.

Differences of Bijections

The American mathematical monthly, 2019
When is a function from an abelian group to itself expressible as a difference of two bijections? Answering this question for finite cyclic groups solves a problem about juggling. A theorem of Marshall Hall settles the question for finite abelian groups,
