Research interests:
Linear algebra, Theory of
matrices, Matrices over function rings.
Direction of scientific researches: factorization
of matrices over function rings; solvability of matrix equations over fields
and commutative rings; investigation a structure of matrices and their
canonical forms over fields and commutative rings with respect to the
similarity and equivalence transformations.
Main scientific results:
1. We present conditions under which a polynomial matrix
of order
over a field
and
, can be factorized in the form
, where
is a monic polynomial matrix and which has a
characteristic polynomial
. In
the case when the desirbed
divisor
exists, a method of constructing it is specified. The conditions under which the
matrix
is uniquely determined by its characteristic
polynomial
are presented.
A
necessary and, for certain classes
of polynomial matrices, sufficient
conditions are established
for the existence
of a common
monic
divisor
with a prescribed characteristic polynomial
of
polynomial matrices
and
.
In the case
when the described
common
divisor
exists,
a method of constructing it is proposed.
2. Let
be the Smith normal form of a matrix
, (
) over a a
domain of principal ideals
. Matrices
and
over a domain of principal ideals
possess the multiplicative property of Smith
normal forms if the Smith normal form of the product of matrices
is equal to the product of the Smith normal forms
of matrices
and
, i.e.
. Necessary and sufficient
conditions are established when the product
is satisfied
. We described the structure of the
factorization of a matrix
, that has the property of multiplicativity
. The structure was investigated for
a matrix and their divisors over a domain of principal ideals in general case
also.
3. We study the structure of matrices over a domain of principal ideals
with respect to the similarity and equivalence
transformations. It is said that a matrix
of order
is diagonalized, if
it is reduced by the similarity transformation to a diagonal form. We establish necessary and sufficient conditions for the diagonalizability
of matrices over a domain
of principal ideals.
The conditions are determined, under which the matrix
is similar to the companion matrix of its
characteristic polynomial. The problems of existence of common eigenvectors and
simultaneous triangularization of a pair of matrices
over a domain of principal ideals with quadratic minimal polynomials are
investigated. The necessary and sufficient conditions of simultaneously triangularization of a pair of matrices with quadratic
minimal polynomials are obtained. As a result, the approach offered provides
the necessary and sufficient conditions of simultaneously triangularization
of pairs of idempotent matrices and pairs of involutory
matrices over a domain of principal ideals.
We give the
canonical form with respect to semiscalar equivalence
for a matrix pencil A(l) = A0 l - A1, where A0 and A1 are n × n matrices over F , and A0
is nonsingular.
4. We established conditions
for solvability of the Riccati
matrix algebraic equation in terms
of the ranks
of matrices constructed in a certain way by
using the coefficients of this equation. We established conditions for the existence
of a unique solution of the matrix polynomial equation A(λ)X(λ) − Y(λ)B(λ) = C(λ) over an
arbitrary field. We propose new necessary and sufficient conditions for the
solvability of a system of linear equations Ax=b
over the domain of principal ideals in terms of (right) Hermite
normal forms of the matrix [ A 0 ]
and [A b ] and an algorithm for the
solution of this system.
