2008 Société Générale trading loss taken massive fraudulent directional positions in 2007 and 2008 far beyond his limited authority" and that the trades involved European stock index futures. Though bank officials say Kerviel apparently worked alone, skeptics question how unauthorized trading of this magnitude could go unnoticed. Kerviel's unassuming background and position have heightened the skepticism that he worked alone. Some analysts suggest that unauthorized trading of this scale may have gone unnoticed initially due to the high volume in low-risk trades normally conducted by his department. The bank said that whenever the fake trades were questioned, Kerviel would describe it as a mistake then
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
