A large class of two-dimensional dilaton-gravity theories in asymptotically AdS₂ spacetimes are holographically dual to a matrix integral, interpreted as an ensemble average over Hamiltonians. Viewing these theories as Jackiw–Teitelboim gravity with a gas of defects, we extend this duality to a broader class of dilaton potentials compared to previous work by including conical defects with small deficit angles. In order to do this we show that these theories are equal to the large p limit of a natural deformation of the (2, p) minimal string theory.

二维膨胀引力、最小弦的变形和矩阵模型

一大类二维膨胀引力理论在渐近 AdS ₂时空中是全息对偶的矩阵积分，被解释为哈密顿量的集合平均。将这些理论视为带有缺陷气体的 Jackiw-Teitelboim 引力，与之前的工作相比，我们通过包括具有小缺陷角的锥形缺陷，将这种对偶性扩展到更广泛的膨胀势。为了做到这一点，我们证明这些理论等于(2, p ) 最小弦理论的自然变形的大p极限。
