String backgrounds and LCFT
We describe a large class of exact string backgrounds with a null Killing vector arising, via a limiting à la Penrose procedure, from string backgrounds corresponding to coset conformal field theories for compact groups GN/HN times a free time-like boson U(1)−N . In this way a class of novel logarithmic conformal field theories (LCFT) emerges, that includes the one constructed recently as an N ...
متن کاملVanishing Theorems and String Backgrounds
We show various vanishing theorems for the cohomology groups of compact hermitian man-ifolds for which the Bismut connection has (restricted) holonomy contained in SU (n) and classify all such manifolds of dimension four. In this way we provide necessary conditions for the existence of such structures on hermitian manifolds. Then we apply our results to solutions of the string equations and sho...
متن کاملHomogeneous Conformal String Backgrounds
We present exact solutions characterised by Bianchi-type I, II, III, V, VI 0 , VI h four-dimensional metric, space-independent dilaton, and vanishing torsion background, for the low energy string eeective action with zero central charge deecit. We show that, in such a context, curvature singularities cannot be avoided, except for the trivial case of at spacetime and constant dilaton. We also pr...
متن کاملString Backgrounds and Homotopy Algebras
String backgrounds are described as purely geometric objects related to moduli spaces of Riemann surfaces, in the spirit of Segal’s definition of a conformal field theory. Relations with conformal field theory, topological field theory and topological gravity are studied. For each field theory, an algebraic counterpart, the (homotopy) algebra satisfied by the tree level correlators, is construc...
متن کاملCosmological String Backgrounds
The propagation of strings in cosmological space-time backgrounds is reviewed. We show the relation of a special class of cosmological backgrounds to exact conformal field theory. Particular emphasis is put on the singularity structure of the cosmological space-time and on the discrete duality symmetries of the string background.
