Hamiltonian Circle Actions with Minimal Fixed Sets
Consider an effective Hamiltonian circle action on a compact symplectic 2n-dimensional manifold (M, ω). Assume that the fixed set M 1 is minimal, in two senses: it has exactly two components, X and Y , and dim(X) + dim(Y ) = dim(M)− 2. We prove that the integral cohomology ring and Chern classes of M are isomorphic to either those of CP or to those of e G2(R), where e G2(R) denotes the Grassman...
متن کاملTopological properties of Hamiltonian circle actions
We study conditions under which a circle action on a symplectic manifold gives rise to an essential (i.e. noncontractible) loop in the group Ham(M,ω) of Hamiltonian symplectomorphisms. A fixed point x of an S-action is called simple if the weights of the linearized action on TxM are 0 or ±1. We show that a circle subgroup that has a simple fixed point x and that is inessential in a semisimple L...
متن کاملThe height of minimal Hilbert bases
For an integral polyhedral cone C = pos{a, . . . , a}, a ∈ Z, a subset B(C) ⊂ C ∩ Z is called a minimal Hilbert basis of C iff (i) each element of C∩Z can be written as a non-negative integral combination of elements of B(C) and (ii) B(C) has minimal cardinality with respect to all subsets of C ∩ Z for which (i) holds. We give a tight bound for the so-called height of an element of the basis wh...
متن کاملNewton polyhedra and Poisson structures from certain linear Hamiltonian circle actions
In this paper we first describe the geometry of the Newton polyhedra of polynomials invariant under certain linear Hamiltonian circle actions. From the geometry of the polyhedra, various Poisson structures on the orbit spaces of the actions are derived and Poisson embeddings into model spaces, for the orbit spaces, are constructed. The Poisson structures, on respective source and model space, a...
متن کاملHilbert C * – systems for Actions of the Circle Group
The paper contains constructions of Hilbert systems for the action of the circle group T using subgroups of implementable Bogoljubov unitaries w.r.t. Fock representations of the Fermion algebra for suitable data of the selfdual framework: H is the reference Hilbert space, Γ the conjugation and P a basis projection on H. According to a general result for Hilbert systems of this type, the group C...
