چکیده
|
In this paper, the type-ii matrices on (negative) latin square graphs are considered andit is proved that, under certain conditions, the nomura algebras of such type-ii matrices are trivial.in addition, we construct type-ii matrices on doubly regular tournaments and show that the nomuraalgebras of such matrices are also trivial.
