چکیده

A q-analogue of de Finetti’s theorem is obtained in terms of a boundary problem for the q-Pascal graph. For q a power of prime this leads to a characterisation of random spaces over the Galois field Fq that are invariant under the natural action of the infinite group of invertible matrices with coefficients from Fq.

De Finetti Coherence and Beyond

The aim of the tutorial is to present the concept of coherence, which dates back to de Finetti, showing its role in managing incomplete (or missing) information. We will start recalling the notion of coherence for (unconditional) probabilities and the related fundamental theorem. Then, in order to generalize this notion to assessments on a set of conditional events, the axiomatic definition of ...

Specializations and Extensions of the Quantum Macmahon Master Theorem

We study some specializations and extensions of the quantum version of the MacMahon Master Theorem derived by Garoufa-lidis, Lê and Zeilberger. In particular, we obtain a (t, q)-analogue for the Cartier-Foata noncommutative version and a semi-strong (t, q)-analogue for the contextual algebra. R ´ ESUMÉ. Nousétudions certaines spécialisations et extensions de la version quantique du " Master The...

A q-ANALOGUE OF THE FOUR FUNCTIONS THEOREM

In this article we give a proof of a q-analogue of the celebrated four functions theorem. This analogue was conjectured by Björner and includes as special cases both the four functions theorem and also Björner’s q-analogue of the FKG inequality.

A q-Analogue of the Centralizer Construction and Skew Representations of the Quantum Affine Algebra

We prove an analogue of the Sylvester theorem for the generator matrices of the quantum affine algebra Uq(ĝln). We then use it to give an explicit realization of the skew representations of the quantum affine algebra. This allows one to identify them in a simple way by calculating their highest weight, Drinfeld polynomials and the Gelfand–Tsetlin character (or q-character). We also apply the qu...
