Double lacunary strongly Cesáro summability method in credibility theory

In the present study, we investigate the relationship between credibility theory and summability theory. Specifically, we introduce the concepts of double lacunary statistically convergent sequences and double strongly lacunary summable sequences involving fuzzy variables. Furthermore, these foundational definitions are supported by a series of important theorems and results that highlight their mathematical significance and potential for broader applications.
