Generalized Perfect Matrices
Alexander Oertel, Achill Schürmann
We generalize Voronoi's theory of perfect quadratic forms to generalized copositive matrices over a full-dimensional closed convex cone K, by introducing a K-copositive minimum and…

On Computing the Copositive Minimum and its Representatives
Alexander Oertel, Achill Schürmann
Computing the copositive minimum of a strictly copositive quadratic form is a natural generalization of computing the arithmetical minimum of a positive definite one. In this paper…
