The irreducible representations (irreps) of the Hecke algebra Hn(q) are shown to be completely characterized by the fundamental invariant of this algebra, Cn. This fundamental invariant is related to the quadratic Casimir operator, C2, of SUq(N), and reduces to the transposition class-sum, [(2)]n, of Sn when q → 1. The projection operators constructed in terms of Cn for the various irreps of Hn...

We study the problem of constructing a probability density in 2N -dimensional phase space which reproduces a given collection of n joint probability distributions as marginals. Only distributions authorized by quantum mechanics, i.e. depending on a (complete) commuting set of N variables, are considered. A diagrammatic or graph theoretic formulation of the problem is developed. We then exactly ...

We discuss in detail the calculation of the leading order QCD corrections to the Effective Hamiltonian which governs b → s γ and b → s g transitions in three different regularization schemes (HV, NDR and DRED). We show that intermediate stages of the calculation do depend on the regularization, but the same scheme independent coefficients can be obtained in all the considered schemes. A detaile...
متن کاملSur le caractère égalitaire de l'allocation de ressources distribuée
The vast majority of multiagent research adressing the problem of the allocation of indivisible goods has concentrated on centralized mechanisms, typically combinatorial auctions. Distributed procedures considers instead that agents locally negotiate by agreeing on deals. In this paper, we consider the restricted negotiation framework consisting of bilateral deals only, and investigate the egal...

On considère la diffusion inélastique de leptons polarisés longitudinalement sur des nucléons polarisés. On note m la masse du lepton , k (k) la 4impulsion du lepton initial (final) et s (s) son 4-vecteur spin covariant , tel que s ·k = 0 (s ·k′ = 0) et s ·s = −1 (s ·s′ = −1); la masse du nucléon est M , sa 4-impulsion et son spin sont P et S. On suppose la dominance de l’échange d’unseul photo...
