Large gauge transformation : ウィキペディア英語版 | Large gauge transformation
Given a topological space ''M'', a topological group ''G'' and a principal G-bundle over ''M'', a global section of that principal bundle is a gauge fixing and the process of replacing one section by another is a gauge transformation. If a gauge transformation isn't homotopic to the identity, it is called a large gauge transformation. In theoretical physics, ''M'' often is a manifold and ''G'' is a Lie group. ==See also== *large diffeomorphism *global anomaly
