Riemannian \(\lambda _1\)-extremal metrics on generalized flag manifolds

  • Kennerson N. S. Lima

摘要

In this work, we will establish new classification results concerning \(\lambda _1\) λ 1 -extremality for partial flag manifolds using a sufficient and necessary condition, in terms of Lie theoretic data, for a Kähler–Einstein metric over a generalized flag manifold to be a critical point for the functional that assigns for each Riemannian invariant Kähler metric its first positive eigenvalue of the associated Laplacian..
