Liouville Lost, Liouville Regained: Central Charge in a Dynamical Background
Several recent approaches to black hole entropy obtain the density of states from the central charge of a Liouville theory. If Liouville theory is coupled to a dynamical spacetime background, however, the classical central charge vanishes. I show that the central charge can be restored by introducing appropriate constraints, which may be interpreted as fall-off conditions at a boundary such as ...
متن کاملLiouville/Toda central charges from M5-branes
We show that the central charge of the Liouville and ADE Toda theories can be reproduced by equivariantly integrating the anomaly eight-form of the corresponding six-dimensional N = (0, 2) theories, which describe the low-energy dynamics of M5-branes.
متن کاملLiouville numbers
In this work, we define the concept of Liouville numbers as well as the standard construction to obtain Liouville numbers and we prove their most important properties: irrationality and transcendence. This is historically interesting since Liouville numbers constructed in the standard way where the first numbers that were proven to be transcendental. The proof is very elementary and requires on...
متن کاملParity Lost and Parity Regained
RAID storage systems protect data from storage errors, such as data corruption, using a set of one or more integrity techniques, such as checksums. The exact protection offered by certain techniques or a combination of techniques is sometimes unclear. We introduce and apply a formal method of analyzing the design of data protection strategies. Specifically, we use model checking to evaluate whe...
متن کاملA note on Liouville theory
An exact differential equation is derived for the evolution of the Liouville effective action with the mass parameter. This derivation is based on properties of the exponential potential and some consequences of the equation are discussed. Liouville theory has been studied for a long time [1] and is currently relevant to two-dimensional quantum gravity or non critical string theory. For a recen...
