note = {We study the vector–axial-vector mixing in a hot medium and its evolution toward the chiral phase transition using different symmetry restoration scenarios based on the generalized hidden local symmetry framework. We show that the presence of the a_1 meson reduces the vector spectral function around the p meson mass and enhances it around the a_1 meson mass. The coupling strength of a_1 to p and πvanishes at the critical temperature due to the degenerate p-a_1 masses. This feature holds rigorously in the chiral limit and still stays intact to good approximation for the physical pion mass.},
