| Research Abstract |
Problems for getting the error term of density theorems related to prehomogeneous vector spaces became clearer. In the quartic case, we have an unpublished result showing a uniform estimate of local orbital integrals. However, in order to use it to reach the error term of the density theorem, more accurate estimate has to be shown to use the inclusion-exclusion principle. For that purpose, we carried out some trial and errors. Also there is some progress in the related local theory on the generalization of the notion of Jordan decomposition.
