... there are only rules known in the Lagrangian and Pieri cases. L. Mihalcea has made progress in finding a geometric Littlewood-Richardson rule in the Lagrangian case, and has suggested that a similar ... Grassmannian and the full flag manifold is the two-step partial flag manifold Fl(k, l, n). This case has appli- cations to Grassmannians of other groups, and to the quantum cohomology of the...

... of bad arcs; see Figure 5. The other case is when an adjacent pair of arcs is contained in an adjacent pair of pants. Once again, a Whitehead move can be applied to reduce the number of bad arcs; ... construct a proper family P of topologically parallel, standardly embed- ded planes in R 3 such that the closed slabs and half spaces determined by P each contains exactly one end of M and ea...
