KPZ Analysis for W3 Gravity
Starting from the covariant action for W3 gravity constructed in [1], we discuss the BRST quantization of W3 gravity. Taking the chiral gauge the BRST charge has a natural interpretation in terms of the quantum Drinfeld–Sokolov reduction for Sl(3, IR). Nilpotency of this charge leads to the KPZ formula for W3. In the conformal gauge, where the covariant action reduces to a Toda action, the BRST...
متن کاملW3: PTSD and War
Post-traumatic stress disorder (PTSD) may develop after a terrifying event involving physical injury or the threat of physical harm in war. Eight years of war after Iraq attacked Iran (between 1980-1988) caused thousands of PTSD among Iranian soldiers as well as civilians. Many of those people are suffering several decades from this form of anxiety most now a complicated form of complex PTSD. Y...
متن کاملThe Effective Action of W3 Gravity to All Orders
The effective action for chiralW3 gravity is studied. It is shown that the computation of the effective action can be reduced to that of a SL(3, IR) Wess-Zumino-Witten theory. If one assumes that the effective action for the Wess-Zumino-Witten model is identical to the WZW action up to multiplicative renormalizations, then the effective action for W3 gravity is, to all orders, given by a constr...
متن کاملThe ZWeb W3 Gateway
This paper describes the design and implementation of a exible and extens-ible framework for providing access to diverse and geographically remote data reserves. This study combines the use of client/server gateways and virtual documents to provide generic client access to remote databases, which may employ diierent data formats and protocols. This exploration has resulted in the construction o...
متن کاملOn Problems of the Lagrangian Quantization of W3-gravity
We consider the two-dimensional model of W3-gravity within Lagrangian quantization methods for general gauge theories. We use the Batalin–Vilkovisky formalism to study the arbitrariness in the realization of the gauge algebra. We obtain a one-parametric non-analytic extension of the gauge algebra, and a corresponding solution of the classical master equation, related via an anticanonical transf...
