Fundamental solutions of the Knizhnik-Zamolodchikov equation of one
variable and the Riemann-Hilbert problem    [PDF]

Shu Oi, Kimio Ueno

In this article, we consider the inverse problem of the connection problem of the KZ equation of one variable. Under some assumptions, this problem is solved recursively as the Riemann-Hilbert problem of additive type and characterizes the multiple polylogarithms of one variable.
