July 21, 2020 Tri Truong (University of Ostrava) On a general definition of the Hukuhara derivatives and some related problems Abstract: (Joint work with Baruch Schneider and Linh Nguyen). The analysis on the time scales is a fairly new area of research. It was introduced in 1988 by Stefan Hilger and his Ph.D. supervisor Bernd Aulbach [1,2]. In this talk, we consider some basic concepts and fundamental properties of time scale calculus and quantum calculus. We propose a new approach being based on the use of the generalized Hukuhara derivatives. We indicate how these ideas extend to the intervalvalued functions on the time scale. Some important properties of generalized deltaHukuhara partial derivative are also discussed. Furthermore, its applications and some relating problems are mentioned. References: [1] B. Aulbach and S.
