Integrability and L^1-convergence of fuzzy trigonometric series with special fuzzy coeffcients

In this paper, we generalize some classical results on the integrability of trigonometric series using the notion of integrability in fuzzy L^1-norm. Here, we introduce new classes of fuzzy coefficients and obtain the necessary and sufficient conditions for L^1-convergence of fuzzy trigonometric series. Also, an example is given for the existence of new classes of fuzzy coefficients.
