Abstract(in English) | Hadamard matrix is defined as a square matrix where any components are $-1$ or $+1$, and where any pairs of rows are mutually orthogonal. In this work, we consider the similar matrix on finite field $GF(p)$ where $p$ is an odd prime. In such a matrix, every component is one of the integers on $GF(p) ¥backslash ¥{0¥}$, that is, $¥{ 1, 2, ¥ldots, p-1¥}$. Any additions and multiplications should be executed under modulo $p$. In this talk, the methods to generate such matrices and some properties of them are chronologically introduced. Some open problems at this moment are also included. |
