Some Convergence Theorems of Uncertain Sequence
Abstract
The emphasis in this paper is mainly on some convergence theorems of uncertain sequence. Firstly, five main types convergence concepts of uncertain sequence: convergence almost surely (a.s.), convergence almost uniformly (a.u.), convergence in uncertain measure, convergence in uncertain distribution and convergence in mean square (ms) are proposed. Secondly, several sufficient and necessity conditions and relations among of convergence concepts are presented. Thirdly, Egorov theorem, monotone convergence theorem, Fatou lemma and bounded convergence theorem of expected value for uncertain sequence on continuous uncertainty space are obtained.

Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
