R.A.Gordon在[1]中定义了从R^1到Banach空间抽象函数的McShane积分,证明了当X不含C0时,如果,在[a,b]上MeShane f可积,则在[a.b]上Pettis可积.在这篇文章中,我们定义了从R^n到Banaach空间抽象函数的Mcshane积分。证明了f McShane可积,则f是Pettis可积.于是我们推广了[1]的结果。 相似文献

<正> §1.1.引言Cauchy 型积分在复变函数论中的重要性不必多说了,它不但有着函数论本身的重要意义,而且是奇异积分方程、边界值问题等学科中不可缺少的工具.但是对于多复变数Cauchy 型积分的研究是不多的.陆启铿与锺同德在[3]中研究了由 Bochner 定义的Cauchy 核所生成的 Cauchy 型积分,并得出了相应的(?)定理.这时候 Cauchy 型积分所定义的函数一般来说并不是解析函数,积分是在区域的整个边界上进行(?) 相似文献

The Convergence of Types Theorem on
d
is wellknown as an important tool for investigations on the limit behaviour of normalized sums or r.v. It is natural to look for a generalization for group-valued r.v. While for simply connected nilpotent Lie groups the Theorem is valid in general the existence of non-trivial compact subgroups causes problems. For compact extensions of nilpotent groups we prove restricted versions of the Convergence of Types Theorem.

This paper investigates fundamental theorems of regular variation (Uniform Convergence, Representation, and Characterization Theorems) some of which, in the classical setting of regular variation in R, rely in an essential way on the additive semigroup of natural numbers N (e.g. de Bruijn's Representation Theorem for regularly varying functions). Other such results include Goldie's direct proof of the Uniform Convergence Theorem and Seneta's version of Kendall's theorem connecting sequential definitions of regular variation with their continuous counterparts (for which see Bingham and Ostaszewski (2010) [13]). We show how to interpret these in the topological group setting established in Bingham and Ostaszewski (2010) [12] as connecting N-flow and R-flow versions of regular variation, and in so doing generalize these theorems to Rd. We also prove a flow version of the classical Characterization Theorem of regular variation. 相似文献

In this paper we present some generalization (at the same time a new and a short proof in the Banach algebra context) of the Weak Spectral Mapping Theorem (WSMT) for non-quasianalytic representations of one-parameter groups.
