报告摘要：We introduce a family of generalizations of the pentagram maps related to Q-nets. We find the map can be treated as a refactorization mapping in the Poisson-Lie group of pseudo-difference operators. Using this description, we obtain the corresponding Lax form with a spectral parameter and invariant Poisson brackets. Finally, we consider the reduction to B-nets and the discrete BKP equation.
