WebSymmetric bilinear forms Joel Kamnitzer March 14, 2011 1 Symmetric bilinear forms We will now assume that the characteristic of our field is not 2 (so 1+1 6= 0). 1.1 Quadratic forms Let H be a symmetric bilinear form on a vector space V. Then H gives us a function Q : V → F defined by Q(v) = H(v,v). Q is called a quadratic form.
In mathematics, a symplectic vector space is a vector space V over a field F (for example the real numbers R) equipped with a symplectic bilinear form. A symplectic bilinear form is a mapping ω : V × V → F that is Bilinear Linear in each argument separately; Alternating ω(v, v) = 0 holds for all v ∈ V; and Non-degenerate ω(u, v) = 0 for all v ∈ V implies that u = 0. WebIn any symplectic vector space, there are many Lagrangian subspaces; therefore, the dimension of a symplectic vector space is always even; if dim V = 2n, the dimension of an …
WebSp(2n,H) is the group of 2n × 2n quaternionic matrices that preserve a nondegenerate skew-symmetric bilinear form on H 2n. Here the "Sp" also stands for "symplectic", but the meaning of "symplectic" here is — at least superficially — completely different from that in our earlier definition of the group Sp(n)!
Much of the theory is available for a bilinear mapping from two vector spaces over the same base field to that field Here we still have induced linear mappings from V to W , and from W to V . It may happen that these mappings are isomorphisms; assuming finite dimensions, if one is an isomorphism, the other must be. When this occurs, B is said to be a perfect pairing.
