Symplectic quotients of unstable Morse strata for normsquares of moment maps

Let K be a compact Lie group and fix an invariant inner product on its Lie algebra k. Given a Hamiltonian action of K on a compact symplectic manifold X with moment map µ: X → k , the normsquare ||µ|| of µ defines a Morse stratification {S : β &#...
