У оквиру серијала предавања Balkan String Webinar, у петак, 17. априла 2026. године у 14 часова, др Сашо Грозданов (Универзитет у Љубљани и Универзитет у Единбургу) одржаће онлајн предавање:
The analytic structure of holographic thermal correlation functions in position and momentum space
САЖЕТАК:
In my talk, I will begin by reviewing the analytic structure of thermal correlation functions in momentum space in holographic setups with black holes. A particular focus will be the discussion of various constraints on such spectra, in particular the spectral duality relation. I will then describe our recent results on understanding the analytic structure in position space, where the singularities of retarded correlators can be understood in the language of the Hadamard theory of differential equations and the behavior of null geodesics. Of particular interest will be the relation between a type of null geodesic, called the bouncing geodesic, and the existence of black hole singularities.
