About coordinates on the phase-spaces of Schlesinger system ($n+1$ matrices, $sl(2,C)$-case) and Garnier--Painlevé 6 systemAbstract: The geometric model of the pathway linking Schlesinger and Garnier--Painlev\'e~6 systems based on an original orthonormalization of a set of elements in ${sl(2,\mathbb C)}$ is constructed. The explicit polynomial map of the Cartesian products of $n-2$ quadrics (the Zariski-topology chart of the phase space of the Garnier--Painlev\'e~6 system) into the phase space of the Schlesinger system and the rational inverse to this map are presented.
