T-duality

==introduction

• 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.[1]
• \(\int \partial X \bar{\partial}X\)
• \(X=X+2\pi R\)
• T-duality
  \(\tilde{R}=\frac{\alpha'}{R}\)
