Conditions for constructing a square matrix that contains a square submatrix with given invariant factors
Necessary and sufficient conditions that (n-k)×(n-k)-matrix A, 1≤k≤n-1, may be augmented to n×n-matrix C with given invariant factors over elementary divisor domains are established. Moreover, we indicated some properties of the invariant factors of matrix C and its submatrix A. Cite as: A. M. Roma...
