Caution should be exercised before displaying ambiguous, challenging art in patient spaces or high-stress waiting and treatment areas (Ulrich, 1999, 2000bb). A growing but limited amount of research on gardens in he...

In this article, we give numerical restrictions on the Chern classes of Ulrich bundles higher-dimensional manifolds, which are inspired by results Casnati in case surfaces. As a by-product, prove that only projective manifolds whose tangent bundle is twisted cubic and Veronese surface. Moreover, cotangent never Ulrich.
