The seminar Symplectic Geometry on the collage of Berne in summer season 1992 confirmed that the subject of this ebook is a really energetic box, the place many various branches of arithmetic come tog9ther: differential geometry, topology, partial differential equations, variational calculus, and intricate research. As traditional in this sort of state of affairs, it can be tedious to assemble all of the valuable constituents. the current publication is meant to offer the nonspecialist an outstanding creation to the hot advancements in symplectic and get in touch with geometry. bankruptcy 1 supplies a assessment of the symplectic staff Sp(n,R), sympkctic manifolds, and Hamiltonian structures (last yet now not least to mend the notations). The 1\Iaslov index for closed curves in addition to arcs in Sp(n, R) is mentioned. This index can be utilized in chapters five and eight. bankruptcy 2 includes a extra certain account of symplectic manifolds commence ing with an explanation of the Darboux theorem asserting that there are not any neighborhood in editions in symplectic geometry. an important examples of symplectic manifolds should be brought: cotangent areas and Kahler manifolds. eventually we speak about the idea of coadjoint orbits and the Kostant-Souriau theorem, that are desirous about the query of which homogeneous areas hold a symplectic constitution.
