标题： Remarks on celestial amplitudes and Liouville theory

摘要： 天体全息理论与Liouville场理论之间的关系被研究。 显示在Liouville关联函数的Coulomb气体实现中出现的不同Selberg型积分之间的对偶关系，会引发一组关于算符维度取值偏移的天体振幅之间的关系$\Delta $。 这是作者在智利圣地亚哥举行的天体全息理论与渐近对称性研讨会（2024年3月4日至6日）上所做的演讲记录。 显示英文摘要

摘要： The relation between celestial holography and Liouville field theory is investigated. It is shown that duality relations between different Selberg type integrals appearing in the Coulomb gas realization of Liouville correlation functions induce a series of relations between celestial amplitudes with shifted values of the operators dimensions $\Delta $. This is a transcript of the talk delivered by the author at the Workshop on Celestial Holography and Asymptotic Symmetries, Santiago de Chile, March 4-6, 2024.
