报告摘要:For Q4, I will describe two exact seed solutions and their tau-functions, specifically, those associated with a deformed elliptic curve (in work with F.W.Nijhoff) and those with prescribed singularity patterns (with N.Joshi). A construction for Q4 will be given involving an intermediary polynomial in which variables and parameters are permuted together by the group of the Fano plane. It connects to a birational group obtained via a procedure of symmetry-completion inspired by 3D consistency. The technique is of interest because this correspond to the group of the elliptic Painleve equation.
