Time‐symmetric cycles [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
The main result of this note is that given any two time‐symmetric cycles, one can find a time‐symmetric extension of one by the other. This means that given a time‐symmetric cycle, both time‐symmetric doubles and square roots can be found.
