摘要

Direct and inverse problem of finding unknown time-moment for mixed wave-diffusion equation involving the Riemann-Liuoville fractional derivative have been targeted for a unique solvability. A solution of a first boundary problem for the time-fractional diffusion-wave equation, obtained using Green’s function, played a key role during evaluations. Certain properties of the Wright-type function were effectively utilized, as well.
