The number of standard forms of matrices over imaginary Euclidean quadratic rings with respect to the $(z,k)$–equivalence

The $(z,k)$--equivalence of matrices over imaginary Euclidean quadratic rings is investigated. The classes of matrices over these rings are selected for which the standard form with respect to $(z,k)$--equivalence is uniquely defined and equal to the Smith normal form. It is established that the num...

description The $(z,k)$--equivalence of matrices over imaginary Euclidean quadratic rings is investigated. The classes of matrices over these rings are selected for which the standard form with respect to $(z,k)$--equivalence is uniquely defined and equal to the Smith normal form. It is established that the number of standard forms over imaginary Euclidean quadratic rings is finite. Bounds for a number of standard forms are established.
