studied. There are considered systems with the Caputo type .-difference operators and with controls which values are from a given convex and bounded subset of the control space. Necessary and sufficient conditions for constrained controllability in finite number of steps are given.虚情假意 发表于 2025-3-23 16:07:52

Garth den Heyerommonly described as diffusional phenomena in the presence of convective motion. Diffusion and mass transfer play a significant role in many materials processing operations. In metal extraction and refining, the chemical changes are usually associated with the transport of the reactants to the react裂口 发表于 2025-3-24 22:29:54
