MONTESINOS, Merced. El problema del tiempo en la relatividad general. Rev. mex. fis. [online]. 2007, vol.53, suppl.2, pp.68-74. ISSN 0035-001X.

The reader is introduced to "the problem of time" present inherently in general relativity. A review of the conceptual fundamentals of both special and general relativity is done with the aim of fixing the conceptual and technical bases required to make the description of the "problem of time". Once this done, it is emphasized the fact that in the context of general relativity the coordinates (or better, the atlas A) which label the points of the manifold do not have per se physical meaning and that this fact requires a suitable form (distinct to the one used in special relativity) of describing the evolution of the degrees of freedom of the dynamical variables involved in a way compatible with the diffeomorphism covariance of the theory.

Keywords : The problem of time; relational evolution; observer.
