Abstract. Through the application of mathematical methods developed in a recent paper,
we obtain a closed expression for the chiral correction to the free energy
of a bag, due to the presence of the external pionic field in a hedgehog
configuration. Low and high temperature developments are given and, in
particular, the zero temperature limit is shown to be consistent with previous
evaluations of the Casimir energy. The subject of renormalization is also
discussed.
