Quadratic Eigenvalue Problems under Conic Constraints
Alberto Seeger · SIAM Journal on Matrix Analysis and Applications · 2011
This paper deals with the analysis of quadratic pencils under conic constraints. To be more precise, one studies an eigenvalue problem of the form [Formula: see text]where [Formula: see text] is a closed convex cone in a Euclidean space, [Formula: see text] refers to the dual cone of [Formula: see text], and [Formula: see text] indicates orthogonality. The matrices [Formula: see text], [Formula: see text], and [Formula: see text], are real but not necessarily symmetric.
