Research Abstract

Codes, Lattices, and Vertex Operator Algebras are important mathematical objects with many similar properties. For example, designs and minimum distances are defined on the three objects. Originally, the coding theory was introduced for the purpose of communication, hence, it has wide application in real life. In this study, I investigated some property of the three objects for some cases. For example, I determined the minimum bounds and classified t-designs for some cases.
