Glossary of symplectic geometry

(Redirected from Symplectic action)

This is a glossary of properties and concepts in symplectic geometry in mathematics. The terms listed here cover the occurrences of symplectic geometry both in topology as well as in algebraic geometry (over the complex numbers for definiteness). The glossary also includes notions from Hamiltonian geometry, Poisson geometry and geometric quantization.

In addition, this glossary also includes some concepts (e.g., virtual fundamental class) in intersection theory that appear in symplectic geometry as they do not naturally fit into other lists such as the glossary of algebraic geometry.

shifted symplectic structure
A generalization of symplectic structure, defined on derived Artin stacks and characterized by an integer degree; the concept of symplectic structure on smooth algebraic varieties is recovered when the degree is zero.[2]
Spectral invariant

An algebraic variety with a symplectic form on the smooth locus.[3] The basic example is the cotangent bundle of a smooth algebraic variety.
symplectomorphism
A symplectomorphism is a diffeomorphism preserving the symplectic forms.

virtual fundamental class
A generalization of the fundamental class concept from manifolds to a wider notion of space in higher geometry, in particular to orbifolds.
