A First Course in String Theory
Represent your answer to part (c) in a spacetime diagram. Show two points related by the identification (2) and the space and time axes for the Lorentz frame in which the compactification is standard.
The identifications and have the same meaning, which is that has no identification at all. In other words, there is NO non-zero real number such that
This identification must be done to both the space and time coordinates. In other words, it cannot be done to only one of and .
