摘要：

We discuss the three-point function in finite temperature field theory. In particular we study the temperature dependence, at the one loop level, of the retarded and advanced vertex functions which can be defined both in the imaginary time and in the real time formalisms. In the high temperature limit the various vertex functions differ, in general, by terms of O(T) which are sensitive to the soft momentum scale.
