Characterizations of Trivial Ricci Solitons
, 2020 Finding characterizations of trivial solitons is an important problem in geometry of Ricci solitons. In this paper, we find several characterizations of a trivial Ricci soliton.

B. Y. Chen-Ricci inequalities for anti-invariant Riemannian submersions in Kenmotsu space forms
Arabian Journal of MathematicsAbstractThe aim of the present paper is to analyze sharp type inequalities including the scalar and Ricci curvatures of anti-invariant Riemannian submersions in Kenmotsu space forms$$K_{s}(\varepsilon )$$Ks(ε). We give non-trivial examples for anti-invariant Riemannian submersions, investigate some curvature relations between the total space and fibres

Some generalizations of RADO'S inequality
, 2011 碩士在本文中，主要以系統化的方式整合文獻資料中與Rado不等式及Popoviciu不等式有相關的不等式。以更簡易的方法(如Jensen不等式和凸函數基本性質)去證明，最後再舉一些例子說明。In this article, mainly in the systematic way to with the Rado''s inequality and Popoviciu''s inequalities are related to inequality.

The geometry of submanifolds in Kähler manifolds is an important research topic. In the present paper, we study submanifolds in complex space forms admitting a semi-symmetric non-metric connection.

On the blow-up of four-dimensional Ricci flow singularities [PDF]
, 2013 textIn 2002, Feldman, Ilmanen, and Knopf constructed the first example of a non-trivial (i.e. non-constant curvature) complete non-compact shrinking soliton, and conjectured that it models a Ricci flow singularity forming on a closed four-manifold.
