Im reading about T-duality in string theory and im trying to understand: in a D dimensional, toroidally, compactified space, is there a symmetry for every compact dimension with itself and with every other compact dimension as well?(adsbygoogle = window.adsbygoogle || []).push({});

So, I know that T-Duality implies symmetry under

[tex] R^i \rightarrow \frac{\alpha'}{R^i} [/tex], for every dimension with itself.

But does it also imply that there is a symmetry under this change between different dimension such as:

[tex] R^1 \rightarrow \frac{\alpha'}{R^2} [/tex] and vice versa?

Im trying to count the number of such symmetries in some D dimensional space.

Thanks,

Ben
