Fyrirlesari: Bergur Snorrason, HÍ Titill: Methods of approximation and their place in pluripotential theory Staðsetning og tími: VR-II 156, föstudaginn 18. oct, kl 11:40 Ágrip: We will discuss several approximation operators and how they can be used to show the regularity of certain extremal functions from pluripotential theory. The tools behind these operators include integral […]

Speaker: Alexia Nix, University of Iceland Date: October 18 Time: 15.00 Place: VRII-156 Title: Wilson loops and precision holography Abstract: The main objective of this talk is the study of holography beyond the conformal paradigm. A specific example of this is realized through the study of 1/2-BPS Wilson loops in maximally supersymmetric Yang-Mills theories on

Speaker: Vyshnav Mohan Date: October 16 Time: 13.00 Place: Oddi-203 Title: Complexity, Bulk Reconstruction, and Semiclassical Black Holes Abstract: Quantum computational complexity is an information-theoretic measure that probes the finer details of the Hilbert space of a quantum system. We will study two of its avatars: Krylov complexity and holographic complexity. We will then show

Speaker: Evangelos Tsolakidis Time and Place: September 16, kl. 13.20, VRII-138 Title: Deformations and Gauge Fields Abstract: Deformations of Quantum Field Theories are an essential tool in our collective attempt to understand the fundamental nature of our universe. They correspond to the so-called interaction terms of a theory, and affect experimentally measurable quantities. In this
