We show that for all but two partitions λ of n > 6 there exists a standard tableau of shape λ with major index coprime to n. In conjunction with a deep result of Kraśkiewicz and Weyman this provides a new purely combinatorial proof of Klyachko’s famous theorem on Lie representations of the general linear group.

We prove a q-analog, which is valid if q is a positive real number, of the following: the probability that, when n tends to infinity, a randomly chosen standard Young tableau of size n contains a fixed standard Young tableau of shape λ ⊢ k is equal to f λ k! (Journal of Combinatorial Theory Series A, volume 97, 117–128, 2002). We also consider pairs of tableaux.

In the paper we find, for certain values of the parameters, the spaces of multipliers ( H(p, q, α), H(s, t, β) ) and ( H(p, q, α), ls ) , where H(p, q, α) denotes the space of analytic functions on the unit disc such that (1 − r)Mp(f, r) ∈ Lq( dr 1−r ). As corollaries we recover some new results about multipliers on Bergman spaces and Hardy spaces. §0. Introduction. Given two sequence spaces X ...

We investigate the nonequilibrium critical behavior of contact process with deterministic aperiodic temporal disorder implemented by choosing healing or infection rates according to a family sequences based on quasiperiodic Fibonacci sequence. This allows us gauge fluctuations via wandering exponent $\omega$ and put our work in context Kinzel--Vojta--Dickman criterion for relevance models. By m...

Résumé. Ces dernières années, la classification croisée ou classification par blocs, c’est-à-dire la recherche simultanée d’une partition des lignes et d’une partition des colonnes d’un tableau de données, est devenue un outil très utilisé en fouille de données. Dans ce domaine, l’information se présente souvent sous forme de tableaux de contingence ou tableaux de co-occurrence croisant les mod...

The analytic signal of a real signal is a standard concept in 1D signal processing. However, the deenition of an analytic signal for real 2D signals is not possible by a straightforward extension of the 1D deenition. There rather occur several diierent approaches in the literature. We review the main approaches and propose a new deenition which is based on the recently introduced quaternionic F...

There are several results concerning double cosets of Young subgroups of symmetric groups which are often proved as corollaries of more general results about Coxeter groups. In this note we give a selection of these results and give them the short combinatorial proofs they deserve. Our replacement for the machinery of Coxeter groups consists of some simple combinatorial arguments involving tabl...
