Versal unfoldings of equivariant linear Hamiltonian vector fields
Published online by Cambridge University Press: 24 October 2008
Abstract
We prove an equivariant version of Galin's theorem on versal deformations of infinitesimally symplectic matrices. Matrix families of codimension zero and one are classified, and the results are used to study the movement of eigenvalues in one parameter families.
