The Linear Inverse Problem for the Three-Dimensional Tricomi Equation in a Prismatic Unbounded Domain

Direct and inverse problems for a parabolic-hyperbolic equation involving Riemann–Liouville derivatives

“…Therefore, inverse problems among the important problems of modern mathematics (see the recent survey paper Liu, Li and Yamamoto [25] and references therein; see also [5], [31], [33]). Inverse problems of various type for partial differential equations of fractional order were studied in the many works (see, for examples, [1]- [6], [11]- [15], [19], [29], [34]- [47]).…”
