Abstract

We present two examples of reductions from the evolution equations describing discrete Schlesinger transformations of Fuchsian systems to difference Painlev\'e equations: difference Painlev\'e equation d-P(A2(1))P\left({A}_{2}^{(1)*}\right) with the symmetry group E6(1){E}^{(1)}_{6} and difference Painlev\'e equation d-P(A1(1))P\left({A}_{1}^{(1)*}\right) with the symmetry group E7(1){E}^{(1)}_{7}. In both cases we describe in detail how to compute their Okamoto space of the initial conditions and emphasize the role played by geometry in helping us to understand the structure of the reduction, a choice of a good coordinate system describing the equation, and how to compare it with other instances of equations of the same type.
