A Classification of Ricci Solitons as (k, μ)-Contact Metrics

Conference paper
Part of the Springer Proceedings in Mathematics & Statistics book series (PROMS, volume 106)


If a non-Sasakian (k, μ)-contact metric g is a non-trivial Ricci soliton on a (2n + 1)-dimensional smooth manifold M, then (M, g) is locally a three-dimensional Gaussian soliton, or a gradient shrinking rigid Ricci soliton on the trivial sphere bundle S n (4) × E n+1, or a non-gradient expanding Ricci soliton with \(k = 0,\mu = 4\). The last case occurs on a Lie group with a left invariant metric, especially for dimension 3, on Sol 3 regarded also as the group E(1, 1) of rigid motions of the Minkowski 2-space.
