On the structure of quantum L∞ algebras

Journal of High Energy Physics, 2017
It is believed that any classical gauge symmetry gives rise to an L∞ algebra. Based on the recently realized relation between classical W $$ \mathcal{W} $$ algebras and L∞ algebras, we analyze how this generalizes to the quantum case.

Understanding conformal field theory through parafermions and Chern Simons theory [PDF]

, 1992
Conformal field theories comprise a vast class of exactly solvable two dimensional quantum field theories. Conformal theories with an enlarged symmetry group, the current algebra symmetry, axe a key ingredient to possible string compactification models ...

Integrable Boundary Flows and the g-function [PDF]

, 2012
This thesis explores renormalisation group flows in integrable quantum field theories with boundaries, as described by the g-function. The main focus is on the g-function in the staircase model, the renormalisation group flow of which passes close to the

Partition functions of perturbed minimal models and background dependent free energy of string field theory [PDF]

, 1991
We calculate the partition function of the (p, p+1) minimal model, perturbed by the operators φ1,3 and φ3,1, to leading order in 1/p, and show that the result agrees with the partition functions of the (p−1,p) and (p+1, p+2) minimal models respectively ...

Localization of Gauge Theories on the Three-Sphere [PDF]

, 2012
We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

Strings, Conformal Field Theory and Noncommutative Geometry [Elektronisk resurs] [PDF]

, 2004
This thesis describes some aspects of noncommutative geometry and conformal field theory. The motivation for the investigations made comes to a large extent from string theory.

The bulk from the boundary; holography and AdS/CFT [PDF]

, 2008
In this thesis we consider various methods by which one can extract (in detail) the metric structure of asymptotically anti-de Sitter spacetime, using only information from the boundary.

Extended defects in curved spacetimes [PDF]

, 1999
This Thesis is concerned with three particular aspects of extended cosmic strings and domain walls in cosmology: their dynamics, gravitation and interaction with a black hole. In Chapter 3, we study the dynamics of an abelian-Higgs cosmic string. We find

Boundary states in conformal field theory [PDF]

, 2004
This licentiate thesis discusses boundary states in conformal field theories related to WZW (Wess-Zumino-Witten) models. These models are used as building blocks to describe the compact extra dimensions of certain string theories.

Towards the super Virasoro minimal string

Journal of High Energy Physics
The (bosonic) Virasoro minimal string, which relates worldsheet string theory to a deformation of the JT gravity matrix model, provides an interesting example of a tractable matrix/string duality.
