摘要
该文研究了在有限温度下量子色动力学中一类Schwinger-Dyson积分方程问题,利用积分方程理论和泛函分析,得到了积分方程解的适定性.进一步,该文证明了手征对称性破缺、保持在量子色动力学中状态转变的临界温度Tc的存在唯一性.
In this paper,we study the Schwinger-Dyson integral equation in quantum chromodynamics under the condition of the finite-temperature.Applying the theory of integral equation and functional analysis,we get the well-posedness of the solution of Schwinger-Dyson integral equation.Furthermore,we prove the existence and uniqueness of critical temperature Tc,which separates the low-temperature phase where the chiral symmetry is spontaneously broken from the high-temperature phase where the chiral symmetry restores in quantum chromodynamics.
