Linear automorphism preserving a cone
Let $V$ be a finite-dimensional real vector space, and let $C\subset V$ be a closed convex cone, not contained in a hyperplane, and such that $C\cap(-C)=\{0\} $. Let $n$ be a nilpotent endomorphism of …

Let $V$ be a real, finite-dimensional vector space, and let $C\subset V$ be a closed convex cone, with nonempty interior, and such that $C\cap (-C)=\{0\} $. Let $u\in\operatorname{GL}(V) $ such that $ …
