We analyze the anti-de Sitter/conformal-field-theory dual geometry of an expanding boost-invariant plasma. We show that the requirement of nonsingularity of the dual geometry for leading and subasymptotic times predicts, without any further assumptions about gauge theory dynamics, hydrodynamic expansion of the plasma with viscosity coefficient exactly matching the one obtained earlier in the static case by Policastro, Son, and Starinets.
我们分析了一个膨胀的 boost 不变等离子体的反德西特/共形场论对偶几何。我们表明，对于主导和次渐近时间，对偶几何无奇异性的要求在没有关于规范理论动力学的任何进一步假设的情况下预测，等离子体的流体动力学膨胀的粘性系数与波利卡斯特罗、索恩和斯塔里内茨早期在静态情况下得到的完全匹配。
