See more Classical mechanics The compact symplectic group Sp(n) comes up in classical physics as the symmetries of canonical coordinates preserving the Poisson bracket. Consider a system of n particles, evolving under See more WebAug 13, 2024 · The symplectic group acts on this space because it acts linearly on $\mathbb{R}^4$. The difference between the symplectic group and the full group of projective automorphisms $\mathrm{PGL}(4,\mathbb{R})$ is that $\mathrm{Sp}(4,\mathbb{R})$ does not act transitively on lines. ...

Note that X is a symplectic vector field, i.e., ι(X)ω is a closed 1-form. When ι(X)ω= dH is an exact 1-form, the corresponding symplectic S1-action is called a Hamiltonian S1-action, and the function H: M→ R is called a moment map. Note that His uniquely determined up to a constant. We point out that a symplectic
