摘要

Abstract 我们研究了具有平行里奇张量的广义萨萨基空间形式（GSSF）（M^{2n+1} (f_1, f_2, f_3)）上的里奇孤子和里奇孤子。我们发现，如果具有 Kenmotsu 度量的 GSSF \(M^{2n+1} (f_1, f_2, f_3) 引入了一个利玛窦孤子或一个 \(\ast\)-Ricci 孤子，那么 \(f_1=-1\) 和 \(f_2=f_3=0\)。此外，利玛窦孤子是膨胀的，而（\ast\）-利玛窦孤子是稳定的。此外，我们还提供了一些例子。

Ricci Solitons on Generalized Sasakian-Space-Forms with Kenmotsu Metric

Abstract

We study Ricci solitons and \(\ast\)-Ricci solitons on generalized Sasakian-space-forms (GSSF) \(M^{2n+1} (f_1, f_2, f_3)\) with parallel \(\ast\)-Ricci tensor. We find that if GSSF \(M^{2n+1} (f_1, f_2, f_3)\) with Kenmotsu metric admits a Ricci soliton or a \(\ast\)-Ricci soliton, then \(f_1=-1\) and \(f_2=f_3=0\). Moreover, the Ricci soliton is expanding, and the \(\ast\)-Ricci soliton is steady. Further, we provide some examples.
