统计收敛与概率测度

早在1951年,H.F ast[6]就引入了统计收敛的定义.之后,出现了许多相关文章(如[4,7-14]等)对统计收敛做了进一步的探索与研究.自上世纪末本世纪初以来,统计收敛作为活跃的领域而得到了深入的研究.例如,统计收敛在数值理论[5],三角级数[15],强可和性[3],局部凸空间[10,13]以及局部紧空间中有界连续函数的理想结构[2]等领域中的讨论.本文通过引入μ-稠密收敛和μ-统计收敛的定义,对于给定一类概率测度U,证明了μ∈U,则序列μ-稠密收敛与统计收敛等价;对μ∈U,序列统计收敛必μ-统计收敛;μ∈U,序列都μ-统计收敛当且仅当序列统计收敛.     

统计收敛的测度理论

建立统计收敛的测度理论已经成为统计收敛研究领域的核心问题, 因为一种合理的理论不仅是把各种统计收敛统一起来, 而且是统计收敛通向测度理论、积分理论、概率论和数理统计的桥梁. 基于这个原因, 首先 证明了由N 的所有子集生成的σ-代数$\mathscr{A}$ 上的所有有限可加概率测度的表示定理; 证明了每个有限可加概率测度都可以唯一的分解为一个可数可加概率测度和一个统计测度(即一个有限可加概率测度μ, 对任意的单 点集{k} 有μ(k)=0)的凸组合. 本文还证明了经典统计测度的许多良好性质, 例如: 由所有经典统计测度组成的集合$\mathscr{S}$ 在$\mathscr{A}$上赋予逐点收敛的拓扑就成为紧凸的~Hausdorff 空间; 每一个经典统计测度都是连续型的~(所以是缺原子的); 对N中的任意子集，每一类特殊的统计测度都满足互余极大极小原理; 每一类统计收敛都可以在统计测度的意义下得到统一.

On Symmetric Spaces With Convergence in Measure on Reflexive Subspaces

A closed subspace H of a symmetric space X on [0, 1] is said to be strongly embedded in X if in H the convergence in X-norm is equivalent to the convergence in measure. We study symmetric spaces X with the property that all their reflexive subspaces are strongly embedded in X. We prove that it is the case for all spaces, which satisfy an analogue of the classical Dunford–Pettis theorem on relatively weakly compact subsets in L₁. At the same time the converse assertion fails for a broad class of separableMarcinkiewicz spaces.

Minimality of Convergence in Measure Topologies on Finite von Neumann Algebras

We prove that the natural embedding of the metric ideal space on a finite von Neumann algebra $\mathcal{M}$ into the *-algebra of measurable operators $\tilde {\mathcal {M}}$ endowed with the topology of convergence in measure is continuous. Using this fact, we prove that the topology of convergence in measure is a minimal one among all metrizable topologies consistent with the ring structure on $\tilde {\mathcal {M}}$ .

Convergence in Conformal Field Theory

Convergence and analytic extension are of fundamental importance in the mathematical construction and study of conformal field theory. The author reviews some main convergence results, conjectures and problems in the construction and study of conformal field theories using the representation theory of vertex operator algebras. He also reviews the related analytic extension results, conjectures and problems. He discusses the convergence and analytic extensions of products of intertwining operators (chiral conformal fields) and of q-traces and pseudo-q-traces of products of intertwining operators. He also discusses the convergence results related to the sewing operation and the determinant line bundle and a higher-genus convergence result. He then explains conjectures and problems on the convergence and analytic extensions in orbifold conformal field theory and in the cohomology theory of vertex operator algebras.     

Convergence Theory for AOR Method

In this paper we give some sufficient conditions for the convergence of the AOR method, introduced by Hadjidimos [5], which include the ones from [1], [2], [5], [6], [7], [9], [10], [11], [12] and which show that the necessary condition given in [8] for the convergence of the AOR method is not valid. We give general conditions for the class of H-matrices, but they are not always easy to check in practice. Consequently, we give some more practical conditions concerning some subclasses of H-matrices.
