The ninth international conference
"Quasilinear Equations, Inverse Problems and their Applications" (QIPA 2023)
(December 4–6, 2023, Moscow Institute of Physics and Technology, Dolgoprudny, Moscow Region)

The conference is dedicated to modern mathematical methods of wave propagation and non-destructive exploration analysis.

The mathematical problems to be discussed at the conference originate from
- different types of tomography (i.e. acoustic tomography, tomography using the elementary particles, electromagnetic tomography),
- analysing the shumpeters dynamics in the economical growth models,
- analysing wave movement, and in particular shock wave dynamics.

During the conference the latest achievements in the fields of quasilinear equations and inverse problems will be discussed, as well as their feasible applications in medicine, geophysics, nanophysics, economical dynamics and transport flow modelling, disperse media physics, etc.
