Abstract
We establish the unique solvability for an inverse problem for semi-linear fractional telegraph equation $$ D^\alpha_t u+r(t)D^\beta_t u-\Delta u=F_0(x,t,u,D^\beta_t u), \quad (x,t) \in \Omega_0\times (0,T] $$ with regularized fractional derivatives $D^\alpha_t u, D^\beta_t u$ of orders $\alpha\in (1,2)$, $\beta\in (0,1)$ with respect to time on bounded cylindrical domain. This problem consists in the determination of a pair of functions: a classical solution $u$ of the first boundary-value problem for such equation, and an unknown continuous coefficient $r(t)$ under the over-determination condition $$ \int_{\Omega_0}u(x,t)\varphi(x)dx=F(t), \quad t\in [0,T] $$ with given functions $\varphi$ and $F$.
