On the Landau-Ginzburg realization of topological gravities
We study the equivariant cohomology of a class of multi-field topological LG 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 theor...
