报告摘要:
Lecture 2 Topics: Periodic reductions, Monodromy matrix
Narrative: By defining periodic initial conditions on a standard staircase, a lattice equation (PΔE) reduces to a mapping (OΔE). The Lax pair for the PΔE gives rise to a Lax pair for the OΔE, whose monodromy matrix can be used to construct integrals for the OΔE.
