WebJan 18, 2004 · Generalized complex geometry, as developed by Hitchin, contains complex and symplectic geometry as its extremal special cases. In this thesis, we explore novel phenomena exhibited by this geometry, such as the natural action of a B-field. We provide new examples, including some on manifolds admitting no known complex or symplectic … WebThen, one can de ne a complex just as above, and the resulting homology is called Floer homology. This is typically not isomorphic to the homology of X, but rather encodes new information usually about a nite dimensional manifold from which Xwas constructed. Floer homology appeared rst in the context of symplectic geometry [Flo87, Flo88c,
WebSymplectic geometry is the study of symplectic manifolds, that is, the study of smooth manifolds equipped with a closed non-degenerate 2-form. More explicitly, a symplectic … WebJan 7, 2024 · In traditional symplectic geometry. In symplectic geometry the analog of Noether’s theorem is the statement that the moment map of a Hamiltonian action which preserves a given time evolution is itself conserved by this time evolution. Souriau called this the symplectic Noether theorem, sometimes it is called the Hamiltonian Noether theorem.
WebIn the field of mathematics known as differential geometry, a generalized complex structure is a property of a differential manifold that includes as special cases a complex structure and a symplectic structure.Generalized complex structures were introduced by Nigel Hitchin in 2002 and further developed by his students Marco Gualtieri and Gil Cavalcanti.
