A Feynman diagram that has three particle intermediate states in all channels is studied. Choosing special values of the masses, in particular taking infrared divergent terms as certain masses go to zero, we explicitly calculate the spectral functions in this limit. They are nonzero in all three reg

The Abelian Higgs model is the simplest available, but it has to be considered in general R, gauges in order to avoid infrared divergences. A full derivation of the appropriate Nielsen identities in such gauges is given. Certain restrictions on the class of allowed R, gauges are found, which resolve

We extend the Lagrangian and generalized linear momentum expressions for time-independent systems found by Kobussen and Leubner and by Yan, respectively, to time-dependent systems. Some examples are presented. Chern-Sitnons Theory in the Schriidinger Representation.
