DESCRIPTION:We consider closed bosonic string theory with flat background 
 and constant H-flux. Up to linear order in the flux\, this is a solution t
 o the string equations of motion and we are able to define a world-sheet c
 onformal field theory framework to compute scattering amplitudes. In the e
 asiest cases of n-point tachyon amplitudes\, we use the properties of the 
 Rogers dilogarithm function to speculate about the nature of the product o
 f functions on spacetimes T-dual to the original configuration.\n\n
