Evaluation of three-dimensional deformation fields of the Earth by methods of the projective differential geometry. The main linear deformations
Aim. The aim is to solve the problem of evaluating the Earth’s topographic surface deformations using
projective differential geometry methods as an expression of the space metric tensor and the group of main linear
deformation parameters in the spatial geocentric coordinate system. Methodology. Solving the problem is based
on using the homeomorphism transformation (mapping) properties of the three-dimensional continuous and
closed domains of the space with the hypothesis that this transformation has a geophysical origin and was caused
