Chiral Rings in Topological (W-)Gravity
نویسندگان
چکیده
We review the superconformal properties of 2d matter coupled to gravity, and extensions thereof. Focusing on topological strings, we recall how the superconformal structure helps to provide a direct link between Liouville theory coupled to matter, and matrix models. We also construct an infinite class of new theories based on W -gravity.

Chiral Rings and Integrable Systems for Models of Topological Gravity
We review the superconformal properties of matter coupled to 2d gravity, and W -extensions thereof. We show in particular how the N = 2 structure provides a direct link between certain matter-gravity systems and matrix models. We also show that much, probably all, of this can be generalized to W -gravity, and this leads to an infinite class of new exactly solvable systems. These systems are gov...
متن کاملGeneralized Drinfeld - Sokolov Hierarchies , Quantum Rings , andW - Gravity
We investigate the algebraic structure of integrable hierarchies that, we propose, underlie models of W-gravity coupled to matter. More precisely, we concentrate on the dispersionless limit of the topological subclass of such theories, by making use of a correspondence between Drinfeld-Sokolov systems, principal sℓ(2) embeddings and certain chiral rings. We find that the integrable hierarchies ...
متن کاملOn the Landau-Ginzburg Realization of Topological Gravities
We study the equivariant cohomology of a class of multi-field topological Landau-Ginzburg models, and find that such systems carry intrinsic information about W -gravity. As a result, we can construct the gravitational chiral ring in terms of LG polynomials. We find, in particular, that the spectrum of such theories seems to be richer than so far expected. We also briefly discuss the BRST opera...
متن کاملTopological Origin of Chiral Symmetry Breaking in QCD and in Gravity
We show that the assumption of non-zero topological susceptibility of the vacuum in a fermion-free version of a theory, such as gravity or QCD, suffices to conclude the following: Once Nf massless fermion flavors are added to the theory, they break the chiral flavor symmetry dynamically, down to a subgroup that would be anomaly-free under gauging; In both theories, the pseudo-Goldstone correspo...
متن کاملTopological Matter in Two Dimensions
Topological quantum field theories containing matter fields are constructed by twisting N = 2 supersymmetric quantum field theories. It is shown that N = 2 chiral (antichiral) multiplets lead to topological sigma models while N = 2 twisted chiral (twisted antichiral) multiplets lead to Landau-Ginzburg type topological quantum field theories. In addition, topological gravity in two dimensions is...
