Abstract
We study modular symmetry anomalies in four-dimensional low-energy effective field theory, which is derived from six-dimensional supersymmetric Yang-Mills theory by magnetic flux compactification. The gauge symmetry is broken to by magnetic fluxes. It is found that an Abelian subgroup of the modular symmetry corresponding to discrete part of can be anomalous, but other elements independent of in the modular symmetry are always anomalyfree.
