We discuss the importance of the axialvector meson in chiral phase transitionat finite temperature. We show that there exists a significant contribution inthe vector spectral function from the axialvector meson through thevector-axialvector mixing in hot matter.Comment: 4 pages, 3 figures, based on presentations given in Quark Matter 2008, Jaipur, India, Feb 4-10, 2008 and the YITP International Symposium "Fundamental Problems in Hot and/or Dense QCD", Kyoto, Japan, March 3-6, 200
