Global uniqueness in a passive inverse problem of helioseismology
A. D. Agaltsov, T. Hohage, R. G. Novikov
We consider the inverse problem of recovering the spherically symmetric sound speed, density and attenuation in the Sun from the observations of the acoustic field randomly excited…

The imaginary part of the scattering Green function: monochromatic relations to the real part and uniqueness results for inverse problems
Alexey Agaltsov, Thorsten Hohage, Roman Novikov
For many wave propagation problems with random sources it has been demonstrated that cross correlations of wave fields are proportional to the imaginary part of the Green function…

Inverse problems in models of resource distribution
Alexey Agaltsov, Evgeny Molchanov, Alexander Shananin
We continue to study the problem of modeling of substitution of production factors motivated by the need for computable mathematical models of economics that could be used as a bas…
