On the eve and afternoon of January 25, 2008, Police raided the Paris headquarters of Société Générale and Kerviel's apartment in the western suburb of Neuilly, to seize his computer files. French
Classifying space for U(n) are in one-to-one correspondence with the homotopy classes of maps from "M" to CP. One also has the relation that that is, BU(1) is the infinite-dimensional projective unitary group. See that article for additional discussion and properties. For a torus "T", which is abstractly isomorphic to U(1) × ... × U(1), but need not have a chosen identification, one writes B"T". The topological K-theory "K"(B"T") is given by numerical polynomials; more details below. Let "F"(C) be the space of orthonormal families of "n" vectors in C and let "G"(C) be the Grassmannian of "n"-dimensional subvector spaces of C. The total
