As a guide, and for the sake of their importance in noncommutative quantum field theory, the spaces R^2N endowed with Moyal products are intensively investigated. Some physical applications, such as the construction of noncommutative Wick monomials and the computation of the Connes-Lott functional action, are given for these noncommutative hyperplanes.engacceso abiertoTriple espectralGeometría no conmutativaCuantización de Moyalartículo original10.1007/s00220-004-1057-z
