Differential substitutions for non-Abelian equations of KdV type
arXiv:2103.04370 · doi:10.13108/2021-13-2-107
Abstract
We construct non-Abelian analogs for some KdV type equations, including the (rational form of) exponential Calogero--Degasperis equation and generalizations of the Schwarzian KdV equation. Equations and differential substitutions under study contain arbitrary non-Abelian parameters.
