Abstract
Let be an inaccessible cardinal, universal algebra, and ∼ the equivalence relation on U κ of eventual equality. From mild assumptions on we give general constructions of End (U κ / ∼) satisfying E=E which do not descend from Δ (U κ) having small strong supports. As an application, there exists an E End (Z κ / ∼) which does not come from a Δ End (Z κ).
