时标上模糊值函数的Nabla-Hukuhara导数
NABLA-HUKUHARA DERIVATIVE OF FUZZY-VALUED FUNCTIONS ON TIME SCALES

本文研究了时标上模糊值函数的Nabla-Hukuhara导数的问题.利用时标理论，获得了关于模糊值函数的Nabla-Hukuhara导数的若干重要性质.这些结果推广并改进了文献[12]中的有关结论.
In this paper, we introduce and investigate the concept of Nabla-Hukuhara derivative of fuzzy-valued functions on time scales. By using the theory of time scales, we show some basic properties of the Nabla-Hukuhara derivative, which extend and improve the related ones in[12]
