# Algebra & Number theory

#### Summary

Number theory is one of the oldest branches of mathematics and is concerned with the properties of numbers in general. In the past few decades, research in number theory has progressed at a rapid rate on many fronts. Number Theory and algebra group of the department of mathematics at POSTECH is highly visible internationally with world class competitive research programs and infrastructure. Our research interest is focused on modular form, automorphic representation, arithmetic of quantum field theory and mirror symmetry and the algebraic coding theory.
