尼耳期．亨利克．阿贝尔 数学
2015/1/21
尼耳期．亨利克．阿贝尔,翻开近世数学的教科书和专门著作，阿贝尔这个名字是屡见不鲜的：阿贝尔积分、阿贝尔函数、阿贝尔积分方程、阿贝尔群、阿贝尔级数、阿贝尔部分和公式、阿贝尔基本定理、阿贝尔极限定理、阿贝尔可和性，等等。很少几个数学家能使自己的名字同近世数学中这么多的概念和定理联系在一起。然而这位卓越的数学家却是一个命途多舛的早夭者，只活了短短的27年。尤其可悲的是，在他生前，社会并没有给他的才能和成...
利用三角范畴的Abel化,引入有限维代数的Abel化等价以及二次导出等价的概念,证明了这2种新的等价与代数的导出等价是一致的.

Abel和对有界变差函数及 ω-型单调函数的逼近
ω-型 有界变差函数 Abel
2009/11/4
研究了Abel和对有界变差函数及其共轭函数的逼近，其逼近结果用有界变差函数的局部全变差来刻画；并由Abel和对有界变差函数及其共轭函数的逼近结果推出了Abel和对Lipα(0＜α≤1) 函数类的逼近阶，同时又得出了Abel和对 -型单调函数及其共轭函数的逼近估计；另外也指出了俞国华文中的错误之处．
