ACOSTA, R.; TUIRAN, E.  e  MOLINA REDONDO, U.. Invarianza de las ecuaciones de movimiento bajo transformaciones de escala espacio-temporales en la dinámica de Newton modificada (MOND). Rev. mex. fis. [online]. 2015, vol.61, n.1, pp.25-31. ISSN 0035-001X.

The basic principles that originated the Modified Newtonian Dynamics MOND, are shown, as well as a description of the fundamentals aspects of the theory: modification of gravity and modification of inertia. Also, it is considered the behaviour of the movement equations under space-temporal scale transformations of the movement equations, that is, transformations that have the form (t,r^→) → (λt,r^→). It was observed in this way that the MOND regime comes from the requirement of the invariance of the movement equations with respect to this transformations.
