| Research Abstract |
The main aim of this research is to study self-dual codes, which are of interest from an algebraic point of view. In self-dual codes, it is a fundamental problem to classify these codes. We completed classifications of several types of self-dual codes using some different approaches. We constructed extremal self-dual codes which have the largest minimum weights among all self-dual codes of that length. Using self-dual codes, we also studied combinatorial designs.
