Abstract
The Goldberger-Treiman relation is shown to persist in the chiral limi t at finite temperatures to O(T2). The T dependence of g(A) turns out to be the same as for F(pi), g(A)(T) = g(A)(0)(1-T2/12F(pi)2), While g (piNN) is temperature independent to this order. The baryou octet D an d F couplings also behave as F(pi) if only pions are massless in the p seudoscalar meson octet.
