GARCIA-COMPEAN, H  e  SOTO-CAMPOS, C. Noncommutative chiral gravitational anomalies in two dimensions. Rev. mex. fis. [online]. 2007, vol.53, suppl.2, pp.120-124. ISSN 0035-001X.

Gravitational anomalies in a noncommutative space are examined. The analysis is generic and independent of a particular noncommutative theory of gravity, and it depends only on how gravity is noncommutatively coupled to chiral fermions. Delbourgo-Salam computation of the gravitational correction of the axial ABJ-anomaly is studied in detail in this context. Finally, we show that the two-dimensional gravitational anomaly does not permit noncommutative corrections in the parameter Θ.

Palavras-chave : Gravitational anomalies; Delbourgo-Salam anomaly; noncommutative field theory.
