Stratified hyperkähler spaces and Nahm's equations
<p>When a compact Lie group acts freely and in a Hamiltonian way on a symplectic manifold, the Marsden-Weinstein theorem says that the reduced space is a smooth symplectic manifold. If we drop the freeness assumption, the reduced space is usually fairly singular, but Sjamaar and Lerman showed...
