چکیده
<p style='text-indent:20px;'>In this paper, we consider an inverse problem of determining a space-dependent source in the time fractional reaction-subdiffusion equation involving locally Lipschitz perturbations, where additional measurements take place at terminal which are allowed to be nonlinearly dependent on state. By providing regularity estimates both and space resolvent operator using local Hilbert scales, establish some results existence uniqueness solutions type stability solution map under consideration. In addition, when input data more regular values, obtain for direct linear above.</p>

Existence and uniqueness in an inverse source problem for a one-dimensional time-fractional diffusion equation
In this study, an inverse source problem for a one-dimensional timefractional diffusion equation is considered. An existence theorem based on the minimization of an error functional between the output data and the additional data is proved. Then it is showed that the unknown source function can be determined uniquely by an additional data u(0, t), 0 ≤ t ≤ T using an auxiliary uniqueness result ...

متن کاملCattaneo-type subdiffusion-reaction equation.
Subdiffusion in a system in which mobile particles A can chemically react with static particles B according to the rule A+B→B is considered within a persistent random-walk model. This model, which assumes a correlation between successive steps of particles, provides hyperbolic Cattaneo normal diffusion or fractional subdiffusion equations. Starting with the difference equation, which describes ...
متن کاملInverse source problem and minimum-energy sources.
We present a new linear inversion formalism for the scalar inverse source problem in three-dimensional and one-dimensional (1D) spaces, from which a number of previously unknown results on minimum-energy (ME) sources and their fields readily follow. ME sources, of specified support, are shown to obey a homogeneous Helmholtz equation in the interior of that support. As a consequence of that resu...
