چکیده
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.

Manifolds with an Su(2)-action on the Tangent Bundle
We study manifolds arising as spaces of sections of complex manifolds fibering over CP 1 with the normal bundle of each section isomorphic to O(k)⊗ Cn. Any hypercomplex manifold can be constructed as a space of sections of a complex manifold Z fibering over CP . The normal bundle of each section must be the sum of O(1)’s, and this suggests that interesting geometric structures can be obtained i...
متن کاملTangent Bundle Embeddings of Manifolds in Euclidean Space
For a given n-dimensional manifold M we study the problem of finding the smallest integer N(M) such that M admits a smooth embedding in the Euclidean space R without intersecting tangent spaces. We use the Poincaré-Hopf index theorem to prove that N(S) = 4, and construct explicit examples to show that N(S) ≤ 3n + 3, where S denotes the n-sphere. Finally, for any closed manifold M, we show that ...
متن کاملA Decomposition Theorem for Projective Manifolds with Nef Anticanonical Bundle
Let X be a simply connected projective manifold with nef anticanonical bundle. We prove that X is a product of a rationally connected manifold and a manifold with trivial canonical bundle. As an application we describe the MRC fibration of any projective manifold with nef anticanonical bundle.
متن کاملMultiplication on the Tangent Bundle
Manifolds with a commutative and associative multiplication on the tangent bundle are called F-manifolds if a unit field exists and the multiplication satisfies a natural integrability condition. They are studied here. They are closely related to discriminants and Lagrange maps. Frobenius manifolds are F-manifolds. As an application a conjecture of Dubrovin on Frobenius manifolds and Coxeter gr...
متن کاملDifferential and Geometric Structure for the Tangent Bundle of a Projective Limit Manifold
The tangent bundle of a wide class of Fréchet manifolds is studied here. A vector bundle structure is obtained with structural group a topological subgroup of the general linear group of the fiber type. Moreover, basic geometric results, known form the classical case of finite dimensional manifolds, are recovered here: Connections can be defined and are characterized by a generalized type of Ch...
