Chen Ming's approach of using group theory to study Goldbach's Conjecture really piqued Zhao Yi's interest.
Group theory is a mathematical method.
As the name suggests, it is the study of groups, and its importance is mainly reflected in abstract algebra. In abstract algebra, many algebraic structures, including rings, fields, and modules, can be seen as being formed by adding new operations and axioms to groups.
Group theory also plays a very important role in other branches of abstract algebra.
Furthermore, in research in the fields of physics and chemistry, many different physical structures, such as crystal structures and hydrogen atom structures, can be modeled using group theoretic methods. As a result, group theory and its related group representation theory have extensive applications in physics and chemistry research.
However, using group theory for number theory research, especially on prime numbers, sounded very novel.
Prime numbers themselves can be seen as a group.
