S. V. Sidorov Lobachevski State University of Nizhni Novgorod
Abstract:
The problem of the similarity of integer matrices with single eigenvalue over the ring of integers is considered. A criterion for a matrix to be similar to a Jordan block is obtained. In addition, a similarity criterion for matrices whose minimal polynomial has degree 2 is obtained.
Keywords:
similarity of matrices, Jordan form, Smith normal diagonal form, ring of integers.
