Kaehler-Ricci solitons on homogeneous toric bundles (I)

Differential Geometry 2007-05-23 v1

Abstract

This is the first of a sequence of two papers. Here, a simple algebraic characterization of the Fano manifolds in the class of homogeneous toric bundles over a flag manifold G^C/P is provided in terms of symplectic data. The result of this paper is used in the second paper, where it is proved that an homogeneous toric bundle over a flag manifold admits a Kaehler-Ricci solitonic metric if and only if it is Fano.

Comments

This is a new version of our previously posted paper "Homogeneous toric bundles with c_1(M)>0". The differences are mainly in the Abstract, Introdution and Title. This new version has been made necessary by the new results given in the next paper "Kaehler-Ricci solitons on homogeneous toric bundles (II)"
