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 interval-valued functions on the time scale. Some important properties of generalized delta-Hukuhara partial derivative are also discussed. Furthermore, its applications and some relating problems are mentioned. References: [1] B.
