3-Commutators Revisited
arXiv:1907.10501
Abstract
We present a class of Pseudo-differential elliptic systems with anti-self-dual potentials on 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.
