چکیده
We construct a recursive formula for a complete system of primitive orthogonal idempotents for any Rtrivial monoid. This uses the newly proved equivalence between the notions of R-trivial monoid and weakly ordered monoid. Résumé. Nous construisons une formule récursive pour un système complet d’idempotents orthogonaux primitifs pour tout monoı̈de R-trivial. Nous employons une nouvelle équivalence entre les notions de monoı̈de R-trivial et de monoı̈de faiblement ordonné.

On the Varieties of Languages Associated with Some Varieties of Finite Monoids with Commuting Idempotents
Eilenberg has shown that there is a one-to-one correspondence between varieties of finite monoids and varieties of recognizable languages. In this paper, we give a description of a variety of languages close to the class of piecewise testable languages considered by I. Simon. The corresponding variety of monoids is the variety of J -trivial monoids with commuting idempotents. This result is the...
متن کاملOn Kiselman Quotients of 0-hecke Monoids
Combining the definition of 0-Hecke monoids with that of Kiselman semigroups, we define what we call Kiselman quotients of 0-Hecke monoids associated with simply laced Dynkin diagrams. We classify these monoids up to isomorphism, determine their idempotents and show that they are J -trivial. For type A we show that Catalan numbers appear as the maximal cardinality of our monoids, in which case ...
متن کاملFinite group algebras of nilpotent groups: A complete set of orthogonal primitive idempotents
We provide an explicit construction for a complete set of orthogonal primitive idempotents of finite group algebras over nilpotent groups. Furthermore, we give a complete set of matrix units in each simple epimorphic image of a finite group algebra of a nilpotent group.
متن کاملOn the Representation Theory of Finite J -trivial Monoids
In 1979, Norton showed that the representation theory of the 0-Hecke algebra admits a rich combinatorial description. Her constructions rely heavily on some triangularity property of the product, but do not use explicitly that the 0-Hecke algebra is a monoid algebra. The thesis of this paper is that considering the general setting of monoids admitting such a triangularity, namely J -trivial mon...
متن کاملEndomorphism Rings of Permutation Modules over Maximal Young Subgroups
Let K be a field of characteristic two, and let λ be a two-part partition of some natural number r. Denote the permutation module corresponding to the (maximal) Young subgroup Σλ in Σr byM . We construct a full set of orthogonal primitive idempotents of the centraliser subalgebra SK(λ) = 1λSK(2, r)1λ = EndKΣr (M ) of the Schur algebra SK(2, r). These idempotents are naturally in one-to-one corr...
