Gauge transformations with fractional winding numbers

The role which gauge transformations of noninteger winding numbers might play in non-Abelian gauge theories is studied. The phase factor acquired by the semiclassical physical states in an arbitrary background gauge field when they undergo a gauge transformation of an ...

Internal symmetries of non-Abelian gauge field configurations
1985-08-15

In a topologically nontrivial gauge theory not all gauge transformations are symmetries (as defined by Forgacs and Manton and by Schwarz) of a given field configuration: first, there may be an obstruction to implement gauge transformations on the fields; next, even those transformations which can be implemented may ...

Non-Abelian Born Infeld action, geometry and supersymmetry
2005-12-01

In this work, we propose a new non-Abelian generalization of the Born Infeld Lagrangian. It is based on a geometrical property of the Abelian Born Infeld Lagrangian in its determinantal form. Our goal is to extend the Abelian second-type Born Infeld action to the non-Abelian form preserving this geometrical ...
