Liouville Theory Revisited
Liouville theory seems to be a kind of universal building block for a variety of models for two-dimensional gravity and non-trivial backgrounds in string theory. Some aspects of it were important for understanding what the matrix models of 2D gravity actually describe (see e.g. [GM]), and it keeps popping up in sometimes unexpected circumstances such as the the physics of membranes in string th...
متن کاملGauge Theory Loop Operators and Liouville Theory
We propose a correspondence between loop operators in a family of four dimensional N = 2 gauge theories on S4 – including Wilson, ’t Hooft and dyonic operators – and Liouville theory loop operators on a Riemann surface. This extends the beautiful relation between the partition function of these N = 2 gauge theories and Liouville correlators found by Alday, Gaiotto and Tachikawa. We show that th...
متن کاملSuper Liouville Theory with Boundary
We study N = 1 super Liouville theory on worldsheets with and without boundary. Some basic correlation functions on a sphere or a disc are obtained using the properties of degenerate representations of superconformal algebra. Boundary states are classified by using the modular transformation property of annulus partition functions, but there are some of those whose wave functions cannot be obta...
متن کاملLiouville Theory and Elliptic Genera
The structure and modular properties of N = 4 superconformal characters are reviewed and exploited, in an attempt to construct elliptic genera-like functions by decompactifying K3. The construction is tested against expressions obtained in the context of strings propagating in background ALE spaces of type AN−1, using the underlying superconformal theory N = 2 minimal ⊗ N = 2 Liouville.
متن کامل2 Liouville Theory with Boundary
We study N = 2 Liouville theory with arbitrary central charge in the presence of boundaries. After reviewing the theory on the sphere and deriving some important structure constants, we investigate the boundary states of the theory from two approaches, one using the modular transformation property of annulus amplitudes and the other using the bootstrap of disc twopoint functions containing dege...
