Indecomposable parabolic bundles
We study the possible dimension vectors of indecomposable parabolic bundles on the projective line, and use our answer to solve the problem of characterizing those collections of conjugacy classes of n×n matrices for which one can find matrices in their closures whose product is equal to the identity matrix. Both answers depend on the root system of a Kac-Moody Lie algebra. Our proofs use Ringel’s theory of tubular algebras, work of Mihai on the existence of logarithmic connections, the Riemann-Hilbert...

Indice du normalisateur du centralisateur d’un élément nilpotent dans une algèbre de Lie semi-simple
L’indice d’une algèbre de Lie algébrique complexe est la codimension minimale de ses orbites coadjointes. Si est semi-simple, son indice, , est égal à son rang, . Le but de cet article est d’établir une formule générale pour l’indice de pour nilpotent, où est le normalisateur dans du centralisateur de . Plus précisément, on obtient le résultat suivant, conjecturé par D. Panyushev :où est le centre de . Panyushev obtient l’inégalité dans Panyushev 2003 et on montre que la maximalité...

Inference for random effects in prime basis factorials using commutative Jordan algebras
Commutative Jordan algebras are used to drive an highly tractable framework for balanced factorial designs with a prime number p of levels for their factors. Both fixed effects and random effects models are treated. Sufficient complete statistics are obtained and used to derive UMVUE for the relevant parameters. Confidence regions are obtained and it is shown how to use duality for hypothesis testing.

Infinite independent systems of identities of alternative commutative algebra over a field of characteristic three
Let 𝔄₃ denote the variety of alternative commutative (Jordan) algebras defined by the identity x³ = 0, and let 𝔖₂ be the subvariety of the variety 𝔄₃ of solvable algebras of solviability index 2. We present an infinite independent system of identities in the variety 𝔄₃ ∩ 𝔖₂𝔖₂. Therefore we infer that 𝔄₃ ∩ 𝔖₂𝔖₂ contains a continuum of infinite based subvarieties and that there exist algebras with an unsolvable words problem in 𝔄₃ ∩ 𝔖₂𝔖₂. It is worth mentioning that these results were...
