Abstract

In this paper we introduce modular symmetric designs and use them to study the existence of Hadamard-Jacket matrices modulo 3/5. We prove that there exist 5-modular Hadamard-Jacket matrices of order n if and only if n≢3.7 (mod 10) and n≢6,11. In particular, this solves the 5-modular version of the Hadamard conjecture.

본 논문에서는 modular 대칭 설계에 대해 소개하고 이를 이용하여 Hadamard-Jacket 행렬의 modular 3/5가 존재한다는 것을 제시한다. 그리고 n차 5-modular Hadamard 행렬의 필요충분조건이 n≢3.7 (mod 10)와 n≢6,11 임을 증명한다. 특히 Hadamard-Jacket 추측(conjecture)에 대한 5-modular 버전을 구한다.
