SYK Seminar, Part IV: Emergent IR Symmetry (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part IV, I discuss how conformal symmetry emerges in the infrared limit.

[Seminar] Resurgent Properties of Minimal Strings and Painlevé Equations (Mr. Roberto Vega, Instituto Superior Tecnico, University of Lisboa)

Title: "Resurgent Properties of Minimal Strings and Painlevé Equations"

Abstract: In this this talk we will introduce the concept of resurgence and how can it be applied to construct global, nonperturbative solutions. As complete examples, we will mention the cases of the Painlevé I and II, while we will end up by focusing on the current state of the Inhomogeneous PII and a q-deformed PII. All these equations (with the exception of the Inhomogeneous PII) appear in the context of Minimal Strings and represent interesting low-dimensional toy models of Quantum Gravity.

Seminar: Topological recursion for tensor models (Prof. Valentin Bonzom (LIPN - Combinatorics, Algorithms and Interactions - Paris University 13)

SYK Seminar, Part III: Effective Action (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part III, I show how to derive the effective action for the master fields G and Σ directly from the partition function.

Seminar: Unitary matrix models (Mr. Neetu, IISER, Bhopal, India)

Title: Unitary matrix models

SYK Seminar, Part II: Melons (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part II, I will discuss the 2-point correlation function and how the large N diagrammatics reduce to iterated melon diagrams.

[Seminar] Matrix Models and Topological Recursion II (Dr. Kento Osuga, University of Sheffield, UK)

Title: Matrix Models and Topological Recursion II

Abstract: Continued from the previous lecture, we will study how the topological recursion was discovered in the study of Hermitian matrix models. More concretely, starting with the spectral curve of a 1-cut Hermitian matrix model, I will present a computational technique that recursively solves loop equations. If time permits, I will make the recursive technique more abstract, and "define" the topological recursion.
