既然Sugeno的Fuzzy测度不具有可加性,那么,就有必要在Fuzzy测度空间上同时引进“几乎”与“伪几乎”这两个概念。由此,对于Fuzzy测度空间上可测函数列的收敛,也相应地出现许多新的内容。本文将讨论这些收敛之间的关系,我们得到的一系列结果推广了经典测度论中相应的定理。我们还发现,[1]中引进的集函数的自连续性这个概念对上述研究起着极为重要的作用,在一些定理中它恰到好创处地替代了经典测度论中可加性这个条件。 相似文献

In this paper we study signed measures. Our main results are as follows: the Fubini theorem is not true in the general case;
the Jordan parts of a transition measure are not necessarily transition measures; the operation of taking the Jordan parts
does not necessarily commute with multiplying by the initial measure; the product of σ-bounded measures need not be a σ-bounded
measure.

Fuzzy random variables have been introduced by Puri and Ralescu as an extension of random sets. In this paper, we first introduce a real-valued generalized measure of the “relative variation” (or inequality) associated with a fuzzy random variable. This measure is inspired in Csiszár's f-divergence, and extends to fuzzy random variables many well-known inequality indices. To guarantee certain relevant properties of this measure, we have to distinguish two main families of measures which will be characterized. Then, the fundamental properties are derived, and an outstanding measure in each family is separately examined on the basis of an additive decomposition property and an additive decomposability one. Finally, two examples illustrate the application of the study in this paper. 相似文献

The concept of finitely additive supermartingales, originally due to Bochner, is revived and developed. We exploit it to study
measure decompositions over filtered probability spaces and the properties of the associated Doléans-Dade measure. We obtain
versions of the Doob–Meyer decomposition and, as an application, we establish a version of the Bichteler and Dellacherie theorem
with no exogenous probability measure.

以非可加模糊测度代替经典可加测度,基于模糊积分建立非线性回归模型是新近出现的数据建模方法.该方法充分考虑自变量因素之间的信息熔合(含协同或冲突)作用.本文完整地给出了适用于实数范围内的基于模糊积分(含Choquet积分和(S)ipo(s)积分)的多元非线性回归模型转化为普通线性回归模型的非线性转换方法及其简化算法.并将该方法应用于金融市场数据分析,结果表明效果较之普通多元线性回归有大的提高,且方法简便容易应用. 相似文献

模糊集的分解集定理有两种形式,第一种形式与模糊集的λ—截集有关:A=其中A_λ是的λ—截集 ̄[1].第二种形式与集合套有关:其中H(λ)为集合套 ̄[2]或者A=其中H(λ)为集合套,Q为(0,1)的可列稠密子集_[3],.其实,这两种形式在本文提出的基本模糊集的概念下,可以统一起来成为任何模糊集可以分解为一些(可数或不可数)基本模糊集的和。不仅如此,本文还提出简单模糊集的概念,并证明了任何模糊集都可以表示成为可数个单调上升的简单模糊集的和,或等价地,可以表示成可数个单调上升的简单模糊集的极限,所用的证明方法是构造性的,所以对模糊集的结构也得出了一个清晰的认识. 相似文献

The perturbation of the generator of a Borel right process by a signed measure is investigated, using probabilistic and analytic
potential theoretical methods. We establish a Feynman-Kac formula associated with measures charging no polar set and belonging
to an extended Kato class. A main tool of this approach is the validity of a Khas’minskii Lemma for Stieltjes exponentials
of positive left continuous additive functionals.

The changes in the unitary polar factor under both multiplicative and additive perturbation are studied. A multiplicative perturbation bound and a new additive perturbation bound, in which a different measure of perturbation is introduced, are presented. 相似文献
