摘要

本文研究了具有几乎里奇孤子的三维余辛流形。我们证明了在三维紧致可定向的无界余辛流形M^3中，在势函数的一定限制下，几乎里奇孤子可化为里奇孤子。因此，我们得到了几个推论。此外，我们还研究了梯度几乎里奇孤子。

On Three Dimensional Cosymplectic Manifolds Admitting Almost Ricci Solitons

In the present paper we study three dimensional cosymplectic manifolds admitting almost Ricci solitons. Among others we prove that in a three dimensional compact orientable cosymplectic manifold M^3 withoutboundary an almost Ricci soliton reduces to Ricci soliton under certain restriction on the potential function lambda. As a consequence we obtain several corollaries. Moreover we study gradient almost Ricci solitons.

期刊介绍： To promote research interactions between local and overseas researchers, the Department has been publishing an international mathematics journal, the Tamkang Journal of Mathematics. The journal started as a biannual journal in 1970 and is devoted to high-quality original research papers in pure and applied mathematics. In 1985 it has become a quarterly journal. The four issues are out for distribution at the end of March, June, September and December. The articles published in Tamkang Journal of Mathematics cover diverse mathematical disciplines. Submission of papers comes from all over the world. All articles are subjected to peer review from an international pool of referees.
