摘要：
We argue that the chiral anomaly of N=1 super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on G(2) holonomy manifolds. We identify an angle of the G(2) background dual to the anomalous U(1)(R) current in field theory. This angle is not an isometry of the metric and we therefore develop a theory of "massive isometry" to describe fluctuations about such angles. Another example of a massive isometry occurs in the Atiyah-Hitchin metric.
