We review the basic notions of compactification in the presence of a back-
ground flux. In extra-dimentional models with more than five dimensions, Scherk
and Schwarz boundary conditions have to satisfy’t Hooft consistency conditions.
Different vacuum configurations can be obtained, depending whether trivial or
non-trivial’t Hooft flux is considered. The presence of the “magnetic” back-
ground flux provide, in addition, a mechanism for producing four-dimensional
chiral fermions. Particularizing to the six-dimensional case, we calculate the
one-loop effective potential for a U(N) gauge theory on M4 × T 2. We firstly
review the well known results of the trivial ’t Hooft flux case, where one-loop
contributions produce the usual Hosotani dynamical symmetry breaking. Finally
we applied our result for describing, for the first time, the one-loop contributions
in the non-trivial’t Hooft flux case.
