Are there string theories based on unidirectional paths or strings?
I ask because the polysigned numbers have some strong unidirectional
In a lattice environment loops are the only way to return to a source
These loops are inherently unidirectional:
The polysigned family naturally supports spacetime.
They do not support an upper limit on higher dimensions.
[Moderator's note: the meaning of this posting is not quite clear to the
moderator but it satisfies the rules of the newsgroup and therefore it is
posted. The closest topic in string theory to Tim's comments are oriented
vs. unoriented strings. Both of them exist in various types of theories.
The fact that Tim does not see, using his simple analogies, why there
should exist constraints on the number of dimensions does not mean that
such a constraint does not exist. Indeed, we can see such constraints
if we look more carefully than Tim. LM]
