Source abstract

Building on the work of P.N. Norton, we give combinatorial formulae for two maximal decompositions of the identity into orthogonal idempotents in the 00-Hecke algebra of the symmetric group, CH0(SN)\mathbb{C}H_0(S_N). This construction is compatible with the branching from H0(SN1)H_0(S_{N-1}) to H0(SN)H_0(S_N). En s'appuyant sur le travail de P.N. Norton, nous donnons des formules combinatoires pour deux décompositions maximales de l'identité en idempotents orthogonaux dans l'algèbre de Hecke H0(SN)H_0(S_N) du groupe symétrique à q=0q=0. Ces constructions sont compatibles avec le branchement de H0(SN1)H_0(S_{N-1}) à H0(SN)H_0(S_N).
