标题： Worldsheet from worldline

摘要： 我们向“微观”推导规范-弦对偶性迈出了一步。 特别是，使用Strebel微分和离散外微积分的数学技术，我们从标量矩阵在d维量子场论的多环费曼图中，在环数发散的极限下，得到了嵌入到d+1维渐近AdS空间中的玻色子弦世界面作用量。 我们的工作建立在't Hooft于1974年启动的计划之上，这次包括全息维度，我们证明该维度来自于费曼图的施温格参数连续体。 显示英文摘要

摘要： We take a step toward a "microscopic" derivation of gauge-string duality. In particular, using mathematical techniques of Strebel differentials and discrete exterior calculus, we obtain a bosonic string worldsheet action for a string embedded in d+1 dimensional asymptotically AdS space from multi-loop Feynman graphs of a quantum field theory of scalar matrices in d-dimensions in the limit of diverging loop number. Our work is building on the program started by 't Hooft in 1974, this time including the holographic dimension which we show to emerge from the continuum of Schwinger parameters of Feynman diagrams.
