Uniqueness of symplectic canonical class , surface cone and symplectic cone of 4 − manifolds with b + = 1
Let M be a smooth, closed oriented 4−manifold. An orientation-compatible symplectic structure on M is a closed two form ω such that ω ∧ ω is nowhere vanishing and gives the orientation. Two such symplectic structures ω 1 and ω 2 on M are said to be deformation equivalent if there is an orientation-preserving diffeomorphism φ such that φ * ω 1 and ω 2 are connected by a path of symplectic forms....

متن کاملComment on “ Symplectic quantization , inequivalent quantum theories , and Heisenberg ’ s principle of uncertainty ”
In Phys. Rev. A 70, 032104 (2004), M. Montesinos and G.F. Torres del Castillo consider various symplectic structures on the classical phase space of the two-dimensional isotropic harmonic oscillator. Using Dirac’s quantization condition, the authors investigate how these alternate symplectic forms affect the quantization of the harmonic oscillator. They claim that these symplectic structures re...
متن کاملSymplectic Hypersurfaces in C
We establish the uniqueness of the symplectic 4-manifolds which admit low degree symplectic embeddings into CP 3. We also discuss the uniqueness of the fundamental group of the complement of such embeddings into arbitrary symplectic 6-manifolds. 2000 Mathematics Subject Classification: Primary 57R17; Secondary 57R95.

In this paper, we investigate the connection between closed Newton-Cotes formulae, trigonometrically-fitted methods, symplectic integrators and efficient integration of the Schr¨odinger equation. The study of multistep symplectic integrators is very poor although in the last decades several one step symplectic integrators have been produced based on symplectic geometry (see the relevant lit...
