• We review recent attempts to understand a possible integrable structure of topological W strings. Topological W matter theory is obtained by twisting the Grassmannian Kazama-Suzuki model. The (unperturbed) chiral ring of physical operators is identified with the cohomology ring of the Grassmannian manifold, which allows a Landau-Ginzburg description. We find the Schubert calculus useful for handling the chiral ring of topological W strings. We try to find out an integrable structure by looking at the perturbed Landau-Ginzberg potential which is expected to describe integrable deformations of ring structure.
