Weyl-Gauging and Conformal Invariance
Scale-invariant actions in arbitrary dimensions are investigated in curved space to clarify the relation between scale-, Weyland conformal invariance on the classical level. The global Weyl-group is gauged. Then the class of actions is determined for which Weyl-gauging may be replaced by a suitable coupling to the curvature (Ricci gauging). It is shown that this class is exactly the class of ac...
متن کاملWeyl Group Invariance and p - brane
In this paper, we study the actions of the Weyl groups of the U duality groups for type IIA string theory toroidally compactified to all dimensions D ≥ 3. We show how these Weyl groups implement permutations of the field strengths, and we discuss the Weyl group multiplets of all supersymmetric p-brane solitons.
متن کاملSchrödinger Invariance and Strongly Anisotropic Critical Systems
The extension of strongly anisotropic or dynamical scaling to local scale invariance is investigated. For the special case of an anisotropy or dynamical exponent θ = z = 2, the group of local scale transformation considered is the Schrödinger group, which can be obtained as the non-relativistic limit of the conformal group. The requirement of Schrödinger invariance determines the two-point func...
متن کاملWeyl invariance and the conductivity of the protoinflationary plasma
We consider a globally neutral Lorentzian plasma as a possible remnant of a preinflationary stage of expansion and pose the problem of the suitable initial conditions for the evolution of the large-scale electromagnetic inhomogeneities. During the protoinflationary regime, the Weyl invariance of the Ohmic current guarantees that the comoving conductivity is approximately constant. The subsequen...
متن کاملWeirdest Martensite: Smectic Liquid Crystal Microstructure and Weyl-Poincaré Invariance.
Smectic liquid crystals are remarkable, beautiful examples of materials microstructure, with ordered patterns of geometrically perfect ellipses and hyperbolas. The solution of the complex problem of filling three-dimensional space with domains of focal conics under constraining boundary conditions yields a set of strict rules, which are similar to the compatibility conditions in a martensitic c...
