alpha^star-Cohomology and Classification of Translation-Invariant
Non-Commutative Quantum Field Theories [PDF]
Amir Abbass VarshoviTranslation-invariant products are studied in the setting of alpha^star-cohomology. It is explicitly shown that all quantum behaviors and especially the scattering matrix of translation-invariant non-commutative quantum field theories are entirely determined by alpha^star-cohomology classes of the star products.View original: http://arxiv.org/abs/1210.0695
