tensor-vector-scalar (TeVeS) theory
     

Fr.:   

A theory put forward to provide a basis for a relativistic generalization of the → MOdified Newtonian Dynamics (MOND) paradigm. TeVeS is based on three dynamical fields: a tensor field, a vector field, and a scalar field. In contrast to general relativity, it has two metrics, an Einstein metric and a physical metric. TeVeS has attracted considerable attention, since it can explain many galactic and cosmological observations without the need for → dark matter. Proposed by J. D. Bekenstein, 2004, "Relativistic gravitation theory for the modified Newtonian dynamics paradigm", Phys. Rev. D, 70, 083509, arXiv:astro-ph/0403694.

tensor; → vector; → scalar; → theory.

  وزن ِ چگالی ِ تانسور   
vazn-e cagâli-ye tânsor

Fr.: poids d'une densité de tenseur   

A constant the value of which is characteristic for any given → tensor density.
