Moore-Penrose inverses of Gram matrices leaving a cone invariant in an indefinite inner product space
Keyword(s):
AbstractIn this paper we characterize Moore-Penrose inverses of Gram matrices leaving a cone invariant in an indefinite inner product space using the indefinite matrix multiplication. This characterization includes the acuteness (or obtuseness) of certain closed convex cones.
