Özet

We prove a fuzzy trigonometric Korovkin type approximation theorem via power series methods of summability and give a related approximation result for periodic fuzzy continuous functions by means of fuzzy modulus of continuity. An illustrative example concerning fuzzy Abel-Poisson convolution operator is also constructed.
