Effects of Income Inequality on Growth through Efficiency Improvement and Capital Accumulation.
In the present paper, the inverted-U shape relationship between growth and inequality found in Chen(2003), is reexamined. We decompose productivity growth into efficiency improvement, capital accumulation and technological progress and then ascertain ...

On the regularity of the Ricci flow
, 2013 本論文包含四章以及附錄。 在第一章中，我們從方程和幾何兩方面來探討瑞奇流的特性，並介紹瑞奇流的演變與基本思想。 我們試圖說明本論文的成果與瑞奇流的正則性之關聯。 我們在第二章利用某類旋轉對稱流形來構造一個奇異點發生在無窮遠處的解。 此外還利用佩雷曼的結果來討論遠古解的無塌陷性質。 在第三章中，我們證明在滿足比昂奇不等式的流形上，瑞奇張量滿足施皖雄型態的一階微分估計。 第四章將用來討論瑞奇孤立子的性質以及它們的分類問題。 我們證明當擴張孤立子的曲率遞減階數超過二次時，其無窮遠切錐為歐氏空間。This ...

Rigidities of Isoperimetric inequality under nonnegative Ricci curvature
The sharp isoperimetric inequality for non-compact Riemannian manifolds with non-negative Ricci curvature and Euclidean volume growth has been obtained in increasing generality with different approaches in a number of contributions [arXiv:1812.05022 ...
