With a view towards applications for de Sitter, we construct the multi-parametric qdeformation of the so(5,C) algebra using the Faddeev-Reshetikhin-Takhtadzhyan(FRT) formalism. [email protected] [email protected]

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 ...

D-branes are classified by twisted K-theory. Yet twisted K-theory is often hard to calculate. We argue that, in the case of a compactification on a simply-connected six manifold, twisted K-theory is isomorphic to a much simpler object, twisted homology. Unlike K-theory, homology can be twisted by a class of any degree and so it classifies not only D-branes but also M-branes. Twisted homology cl...

The main subject of this thesis is the physics of spin glasses. Spin-glass models have been introduced in the 70s in order to describe the behavior of dilute magnetic alloys. Afterwards it has been discovered that some spin-glass models could be considered prototype models to understand the behavior of supercooled liquids. More recently, a close analogy between combinatorial optimization proble...
