For polyhedral cones in the Euclidean space, we present its conic dimension, which is invariant under linear isomorphisms that is sensitive to the number of generators of this cone, and the related...

In the present paper, we will characterize linear maps of M n ( F ) , the ring of all n × n matrices over an algebraically closed field F of characteristic zero, which preserve the set of all algeb...

A distinguished class of polyhedral cones is considered. For a linear operator $$\mathcal {L}$$ preserving a cone in this class, we prove, under some assumption on the number of edges of the cone, that its spectrum contains exactly one strictly posit
