Buscher rules (source code)

= Buscher rules
{c}

The <Buscher rules> invert the metric component along an Abelian isometry and transform the other metric and B-field components. The Gaussian <functional determinant> also shifts the dilaton; when the metric is block diagonal with $G_{zz}=V$, $\widetilde\Phi=\Phi-\tfrac12\log V$.
