Complementarity of Kinematics and Geometry in General Relativity Theory

Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functional arbitrariness when integrability condition for spin tensor is satisfied. Some aspects of geometrization principle and geometrical conventionalism of Poincare are discussed in a light of the obtained results.Comment: The paper is developed version of talk, presented at the conference RusGrav-2010 (June 2010, Moscow), submitted to GR
