• 10-20/10/2026 S. Jakšić continued with the work started in September. Based on the previous study of the fractional Hankel transform in collaboration with S. Maksimović, S. Atanасova, and S. Pilipović, the aim is to investigate fractionalized differential equations and solve them using the fractional Hankel transform. Our motivation comes from the fact that fractionalization can provide a more general description of physical processes. For example, a classical differential equation may describe motion in a particular medium, whereas its fractionalized counterpart may capture motion in more complex or heterogeneous environments.
