Ten chapters discuss the skew field of quaternions; elements of the geometry of S3, Hopf bundles, and spin representations; internal variables of singularity free vector
fields in a Euclidean space; isomorphism classes, Chern classes, and homotopy classes of singularity free vector
fields in 3-space; Heisenberg algebras, Heisenberg groups, Minkowski metrics, Jordan algebras, and special linear groups; the Heisenbreg group and natural C*-algebras of a vector field in 3-space; the Schrodinger representation and the metaplectic representation; the Heisenberg group as a basic geometric background of signal analysis and geometric optics; quantization of quadratic polynomials; and field theoretic Weyl quantization of a vector field in 3-space.
Corel will initially offer 10,000 free vector
images and 100,000 free web images and is developing a full-blown subscription model for the clipart which it will unveil on May 13 at E3, the Electronic Entertainment Expo in Las Vegas.
Therefore the readership ranges from graduate students to professionals and the scope is necessarily fairly wide, covering such topics as Lagrangian formalism and the momentum picture, free scalar fields (including neutral scalar fields), arbitrary scalar fields, free spinor fields, free vector
fields, and connotation relations for free fields.
