Multidimensional quasi strongly summability in credibility theory
提出了可信性理论框架下双重拟统计收敛的概念，研究其与其他收敛类型的关系，为二维模糊系统提供新见解。
Abstract This paper proposes the concept of double quasi-statistical convergence within the framework of credibility theory. Quasi-statistical convergence, as a generalization of statistical convergence, plays a key role in capturing more generalized and intricate patterns of convergence in fuzzy variables. Extending earlier studies, we develop this notion for double sequences and examine its connections with other convergence types in credibility theory, providing new insights into two-dimensional fuzzy systems
