Inversion of dynamic topography and geoid for mantle viscosity, analyses of see-level data and their relationship to
postglacial rebound, inversions of gravity and seismic data to determine the crustal structure and others are
classical problems used in contemporary geodynamics research. The lecture presents the basic theory of these
inverse problems, discuss their advantages and limitations and gives overview about the basic literature in this
field.
