Semisimple Hopf algebras of dimension $9q^2$ and high-dimensional semisimple Hopf algebras of Frobenius type

Abstract

Let $k$ be an algebraically closed field of characteristic 0. In this paper, we obtain the structure theorems for semisimple Hopf algebras of dimension $9q^2$ over $k$, where $q$ is a prime number. We also prove that odd-dimensional semisimple Hopf algebras over $k$ of dimension less than 600 are of Frobenius type.

arXiv commentThe present paper is not well written. The author has rewritten it, and the result is that this paper will be contained in another paper
