摘要: Gravitational axial and chiral anomalies in a noncommutative space are examined through the explicit perturbative computation of one-loop diagrams various dimensions. The analysis depend on how gravity is coupled to matter fields. DelbourgoSalam gravitational anomaly contribution pion decay into two photons, studied detail this context. In process we show that two-dimensional pure Weyl does not receive corrections. Pure 4k + 2 dimensions with fields being fermions spin- 1 3 , discussed correction found both cases. Mixed finally considered for
