چکیده
We construct examples to show that having nef cotangent bundle is not preserved under finite ramified covers. Our also a projective manifold with Stein universal cover may have bundle, disproving conjecture of Liu–Maxim–Wang [7].

Dirac Cotangent Bundle Reduction
The authors’ recent paper in Reports in Mathematical Physics develops Dirac reduction for cotangent bundles of Lie groups, which is called Lie– Dirac reduction. This procedure simultaneously includes Lagrangian, Hamiltonian, and a variational view of reduction. The goal of the present paper is to generalize Lie–Dirac reduction to the case of a general configuration manifold; we refer to this as...
متن کاملA cotangent bundle slice theorem
This article concerns cotangent-lifted Lie group actions; our goal is to find local and “semi-global” normal forms for these and associated structures. Our main result is a constructive cotangent bundle slice theorem that extends the Hamiltonian slice theorem of Marle [C.-M. Marle, Modèle d’action hamiltonienne d’un groupe de Lie sur une variété symplectique, Rendiconti del Seminario Matematico...
متن کاملThe Orbit Bundle Picture of Cotangent Bundle Reduction
Cotangent bundle reduction theory is a basic and well developed subject in which one performs symplectic reduction on cotangent bundles. One starts with a (free and proper) action of a Lie group G on a configuration manifold Q, considers its natural cotangent lift to T ∗Q and then one seeks realizations of the corresponding symplectic or Poisson reduced space. We further develop this theory by ...
متن کاملMurre’s Conjectures and Explicit Chow–künneth Projectors for Varieties with a Nef Tangent Bundle
In this paper, we investigate Murre’s conjectures on the structure of rational Chow groups and exhibit explicit Chow–Künneth projectors for some examples. More precisely, the examples we study are the varieties which have a nef tangent bundle. For surfaces and threefolds which have a nef tangent bundle explicit Chow–Künneth projectors are obtained which satisfy Murre’s conjectures and the motiv...
