Résumé

We show how, for certain Harish-Chandra modules, the polynomial giving the dimension of the Dirac index of the corresponding coherent family can be expressed as an integer linear combination of the coefficients of the characteristic cycle. This is joint work with S.Mehdi, D.Vogan and R.Zierau.
