Singularities of integrable Hamiltonian systems with the same boundary foliation. An infinite series
M. A. Tuzhilin Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
Four-dimensional momentum map singularities of integrable Hamiltonian systems of two degrees of freedom are considered. A construction of an infinite series of pairs of 4-dimensional saddle-saddle singularities is provided so that 4-singularities are not Liouville equivalent in each pair and the 2-foliations on their 3-boundaries are Liouville equivalent.
Key words:
Liouville equivalence, almost direct product of atoms, circular molecules, saddle-saddle singularities of the momentum map.
