Title: (1,2)-symplectic metrics, flag manifolds and tournaments
Author: Cohen, N
Negreiros, CJC

Abstract: It has recently been shown by Mo and Negreiros that a necessary condition for an invariant almost complex structure on the complex full flag manifold IF(n) to admit a (1,2)-symplectic invariant metric is that its associated tournament be cone-free. In this paper, a canonical stair-shaped form is given for such tournaments, and this is applied to show that the condition is also sufficient; in the process, all the associated (1, 2)-symplectic metrics are described.
