Towards noncommutative integrable equations
We present a powerful method to generate various equations which possess the Lax representations on noncommutative (1+1) and (2+1)-dimensional spaces. The generated equations contain noncommutative integrable equations obtained by using the bicomplex method and by reductions of the noncommutative (anti-)self-dual Yang-Mills equation. This suggests that the noncommutative Lax equations would be integrable and be derived from reductions of the noncommutative (anti-)self-dual Yang-Mills equations, which implies the noncommutative version of Ward's conjecture.
