Uniqueness for an inverse problem of determining order and temporal factor of the source for time-fractional evolution equations
Ravshan Ashurov, Masahiro Yamamoto
This paper addresses the inverse problem of simultaneously recovering the fractional order and the time-dependent source factor in the Cauchy problem…

An initial-boundary problem for a mixed fractional wave equation
Erkinjon Karimov, Nasser Al-Salti, Muna Al-Ghabsi
We aim to prove a unique solvability of an initial-boundary value problem (IBVP) for a time-fractional wave equation in a rectangular domain. We exploit the spectral expansion meth…

On generalized Mittag-Leffler-type functions of two variables
Anvar Hasanov, Erkinjon Karimov
We aim to study Mittag-Leffler type functions of two variables by analogy with the Appell hypergeometric functions of…
