%0 Journal Article %T Using Dual Double Fuzzy Semi-Metric to Study the Convergence %J Applied System Innovation | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/asi2020013 %X Convergence using dual double fuzzy semi-metric is studied in this paper. Two types of dual double fuzzy semi-metric are proposed in this paper, which are called the infimum type of dual double fuzzy semi-metric and the supremum type of dual double fuzzy semi-metric. Under these settings, we also propose different types of triangle inequalities that are used to investigate the convergence using dual double fuzzy semi-metric.
