  摘要：Multiplicity-free actions are symplectic manifolds with a very high degree of symmetry. Delzant [2] showed that all compact multiplicity-free torus actions admit compatible Kahler structures, and are therefore toric varieties. In this note we show that Delzant's result does not generalize to the non-abelian case. Our examples are constructed by applying U(2)-equivariant symplectic surgery to the flag variety U(3)/T-3. We then show that these actions fail a criterion which Tolman [9] shows is n...

  摘要：Let H subset of G be real reductive Lie groups and pi an irreducible unitary representation of G. We introduce an algebraic formulation (discretely decomposable restriction) to single out the nice class of the branching problem (breaking symmetry in physics) in the sense that there is no continuous spectrum in the irreducible decomposition of the restriction pi/(H). This paper offers basic algebraic properties of discretely decomposable restrictions, especially for a reductive symmetric pair (...
