Abstract: We consider the ill-posed problem for a plasma inhomogeneity, which is diagnosed by the reflected diffraction field, i.e., backscattering from the irradiated object. In this case, there is no need for a more accurate renewal… read more here.

DOI: 10.1134/s1995080221030069
Abstract: An inverse problem for determining the order of time-fractional derivative in a nonhomogeneous subdiffusion equation with an arbitrary elliptic differential operator with constant coefficients in $$N$$ -dimensional torus is considered. Using the classical Fourier method… read more here.
