Lur’e equations and even matrix pencils

open access: yesLinear Algebra and its Applications, 2011
The set of solutions of Lur'e equations in terms of deflating subspaces of even matrix pencils is characterized. It is shown that there exist special extremal solutions in terms of definiteness and a procedure to construct these solutions via deflating subspaces of even matrix pencils is formulated.
