Simultaneous determination of initial value and source term for time-fractional wave-diffusion equations

Paola Loreti, Daniela Sforza, Masahiro Yamamoto

We consider initial boundary value problems for time fractional diffusion-wave equations: $d_{t}^{α} u = - A u + μ (t) f (x)$ in a bounded domain where $μ (t) f (x)$ describes a source and…

A Carleman estimate and an energy method for a first-order symmetric hyperbolic system

G. Floridia, H. Takase, M. Yamamoto

For a symmetric hyperbolic system of the first order, we prove a Carleman estimate under some positivity condition concerning the coefficient matrices. Next, applying the Carleman…
