Integrable Boundary for Quad-Graph Systems: Three-Dimensional Boundary Consistency
Vincent Caudrelier, Nicolas Crampé, Qi Cheng Zhang
We propose the notion of integrable boundary in the context of discrete integrable systems on quad-graphs. The equation characterizing the boundary must satisfy a compatibility equ…
