Generalized Complex Hamiltonian Torus Actions: Examples and Constraints
Consider an effective Hamiltonian torus action T ×M → M on a topologically twisted, generalized complex manifold M of dimension 2n. We prove that the rank(T ) ≤ n − 2 and that the topological twisting survives Hamiltonian reduction. We then construct a large new class of such actions satisfying rank(T ) = n − 2, using a surgery procedure on toric manifolds.
متن کاملExamples of Non-kähler Hamiltonian Torus Actions
An important question with a rich history is the extent to which the symplectic category is larger than the Kähler category. Many interesting examples of non-Kähler symplectic manifolds have been constructed [T] [M] [G]. However, sufficiently large symmetries can force a symplectic manifolds to be Kähler [D] [Kn]. In this paper, we solve several outstanding problems by constructing the first sy...
متن کاملNon-Hamiltonian symplectic torus actions
An action of a torus T on a compact connected symplectic manifold M is Hamiltonian if it admits a momentum map, which is a map on M taking values in the dual of the Lie algebra of T. In 1982, Atiyah and GuilleminSternberg proved that the image of the momentum map is a convex polytope, now called the momentum polytope. In 1988, Delzant showed that if the dimension of T is half of the dimension o...
متن کاملGeneralized honeycomb torus is Hamiltonian
Generalized honeycomb torus is a candidate for interconnection network architectures, which includes honeycomb torus, honeycomb rectangular torus, and honeycomb parallelogramic torus as special cases. Existence of Hamiltonian cycle is a basic requirement for interconnection networks since it helps map a “token ring” parallel algorithm onto the associated network in an efficient way. Cho and Hsu...
متن کاملTall Complexity One Hamiltonian Torus Actions
We study torus actions on symplectic manifolds with proper moment maps in the case that each reduced space is two-dimensional. We provide a complete set of invariants for such spaces.
