「We thus have a notion of a τ function associated to an algebraic curve. Suchnotion has already been encountered in the litterature [9], and it is not clear whetherour definition coincides with other existing definitions. What can be understood sofar, is that we are defining a sort of quantum deformation of a classical τ -functionwhose spectral curve is E.」
とあるので、比較してみたいところだ。
