3-Commutators Revisited

Abstract

We present a class of Pseudo-differential elliptic systems with anti-self-dual potentials on $\mathbb{R}$ satisfying compensation phenomena similar to the ones for elliptic systems with anti-symmetric potentials. These compensation phenomena are based on new "multi-commutator" structures generalizing the 3-commtators introduced by the authors in a previous work some years ago.
