实分析中某些不同定理的统一技巧

本文针对与Ｌｅｂｅｓｇｕｅ可测函数列收敛性有关的重要定理,都使用纯集合描述的统一方式重新进行了论证,此作法不仅在形式有某种新意,更重要的是此作法揭示了函数的各种收敛性的集合特征及各种收敛的本质联系与区别。     

Weierstrass过程的Hermite-Fejēr插值算子的收敛性

本文首先讨论了以第二类chebyshev多项式Un(x)的零点为插值节点的Weierstrass过程的Hermite-Fej叆ｒ插值算子Ｈｉ,n(f,x) ,然后证得Hi,n(f,x)是Weierstrass过程 ,并给出其敛速度的估计     

Kuhnian theory-choice and virtue convergence: Facing the base rate fallacy

Perhaps the strongest argument for scientific realism, the no-miracles-argument, has been said to commit the so-called base rate fallacy. The apparent elusiveness of the base rate of true theories has even been said to undermine the rationality of the entire realism debate. On the basis of the Kuhnian picture of theory choice, I confront this challenge by arguing that a theory is likely to be true if it possesses multiple theoretical virtues and is embraced by numerous scientists–even when the base rate converges to zero.     

具有可列奇点的无穷积分收敛的一个判别法

本文在瑕积分中推广了积分中值定理，并利用它证明了一类具有可列奇点的无穷积分收敛的一个充分条件．     

由依概率收敛推出γ阶收敛的条件

设ζn依概率收敛于ζ，众所周知，此时ζn未必r阶收敛于ζ；如果给ζn附加一些另外条件，则ζn可r阶收敛于ζ，本文证明了几个这样的定理，它们推广了有关文献中的类似定理．
