Initial value problems for quad equations
journal contributionposted on 25.03.2022, 05:54 authored by Pieter Van Der KampPieter Van Der Kamp
We describe a method to construct well-posed initial value problems (IVPs) for not necessarily integrable equations on not necessarily simply connected quad-graphs. Although the method does not always provide a well-posed IVP (not all quad-graphs admit well-posed IVPs) it is effective in the class of rhombic embeddable quad-graphs.
