在这篇注记中，我们考虑了D = 2，3，4中的约束规范理论，这些规范理论是由S_2或T_2紧化高维共形场理论与引力对偶定义的。我们研究了这些理论在de Sitter时空中作为哈勃参数的函数的行为。我们发现，在每种情况下，当哈勃参数增加到一个临界值以上时，场论的德西特真空态(由球体的欧几里得延拓定义)经历一个解禁闭相变。在每种情况下，相应的临界De Sitter温度都比相应的Minkowski空间去禁闭温度小一个几乎等于De Sitter时空维度的因子。这种行为在定性和定量上都类似于最近在ARXIV：1007.3996中研究的由CFT的S1紧凑化定义的约束理论。
In this note, we consider confining gauge theories in D = 2, 3, 4 defined by S2 or T2 compactification of higher-dimensional conformal field theories with gravity duals. We investigate the behavior of these theories on de Sitter spacetime as a function of the Hubble parameter. We find that in each case, the de Sitter vacuum state of the field theory (defined by Euclidian continuation from a sphere) undergoes a deconfinement transition as the Hubble parameter is increased past a critical value. In each case, the corresponding critical de Sitter temperature is smaller than the corresponding Minkowski-space deconfinement temperature by a factor nearly equal to the dimension of the de Sitter spacetime. The behavior is qualitatively and quantitatively similar to that for confining theories defined by S1 compactification of CFTs, studied recently in arXiv:1007.3996.
