Is the bounded rank perturbations problem for matrix pencils just a completion problem?

In this paper, we study a direct link between the bounded rank perturbations problem and the completion problem for matrix pencils. We conjecture that the bounded rank perturbations problem is, in fact, equivalent to a completion problem. We prove the conjecture in three cases: when the rank bound is one, when the involved pencils are of full row rank, and when the rank bound equals the rank distance of the involved matrix pencils.

Abstract

In this paper, we study a direct link between the bounded rank perturbations problem and the completion problem for matrix pencils. We conjecture that the bounded rank perturbations problem is, in fact, equivalent to a completion problem. We prove the conjecture in three cases: when the rank bound is one, when the involved pencils are of full row rank, and when the rank bound equals the rank distance of the involved matrix pencils.
