abstract

In this paper, we investigate the nature of Einstein solitons, whether it is steady, shrinking or expanding on almost $\alpha$-cosymplectic $3$-manifolds. We also prove that a simply connected homogeneous almost $\alpha$-cosymplectic $3$-manifold, admitting a contact Einstein soliton, is an unimodular semidirect product Lie group. Finally, we show that a harmonic manifold admits a Ricci soliton if and only if it is flat.

  1. Some Characteristics of Almost $\omega$-Bach Solitons

    math.DG 2025-05 reject novelty 5.0 of 10

    A new generalized Bach soliton is defined, but the explicit examples on S2 x H2, R2 x H2, and R2 x S2 do not satisfy the governing equations.
