Ensaio sobre a unidimensionalidade do tempo
  Some ideas aimed to understand that time is one-dimensional are briefly reviewed. Some attempts to construct theories in varieties with more spatial and temporal components are presented. It is discussed, from the epistemological point of view, which path can be taken to try to "prove" the one-dimensionality of time (or the three-dimensionality of space) from these generalized theories.
