Let X denote a real Banach space, X \* its dual space and V an n-dimensional subspace of X. Given a weak \* -closed cone S \* ⊂ X \* , we say that f ∈ X has shape if f, φ 0 for all φ ∈ S \* . Let S ⊂ X denote the cone of elements having shape. Suppose the linear operator P : V → V leaves S invariant
