introduction
- the T stands for toroidal
- This refers to the situation where one string theory compactified on a circle of radius R, and another string theory compactified on circle of radius 1/R describe the same physics. Therefore when one of the theories is on a very small circle the other theory is on a very large circle.
- \(\int \partial X \bar{\partial}X\)
- \(X=X+2\pi R\)
- T-duality
\[\tilde{R}=\frac{\alpha'}{R}\]
