Lectures on W - Gravity , W - Geometry and W - Strings ⋆
Classical W-gravities and the corresponding quantum theories are reviewed. W-gravities are higher-spin gauge theories in two dimensions whose gauge algebras are W-algebras. The geometrical structure of classical W-gravity is investigated, leading to surprising connections with self-dual and special geometry. The anomalies that arise in quantum W-gravity are discussed, with particular attention ...
متن کاملA representation for some groups, a geometric approach
In the present paper, we are going to use geometric and topological concepts, entities and properties of the integral curves of linear vector fields, and the theory of differential equations, to establish a representation for some groups on $R^{n} (ngeq 1)$. Among other things, we investigate the surjectivity and faithfulness of the representation. At the end, we give some app...
متن کاملAnomaly-free W-gravity Theories
We give a review of some recent developments in the quantisation of W-gravity theories. In particular, we discuss the construction of anomaly-free W ∞ and W 3 gravities.
متن کاملEffects of TeV Scale Gravity on e+e− → W+W−
We study the process e+e− → W+W− to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin2 graviton and spin-1 SM gauge boson exchange terms, even when rightpolarised electron beam is used. Our analysis shows that larger than 5% asymmetry is possible at a linear collider wi...
متن کاملA geometric approach to finding new lower bounds of A(n, d, w)
Certain classes of binary constant weight codes can be represented geometrically using linear structures in Euclidean space. The geometric treatment is concerned mostly with codes with minimum distance 2(w − 1), that is, where any two codewords coincide in at most one entry; an algebraic generalization of parts of the theory also applies to some codes without this property. The presented theore...
