İzole olmayan hiperyüzey tekilliklerinin jet şemaları

In this thesis, we construct the jet schemes of some non-isolated hypersurface singularities in C^3 and some isolated surface singularities in C^4 which appear as the normalisation of our non-isolated singularity. We want to determine the jet scheme structure in these. The singularities we consider are called rational triple singularities. They are of 9 types. In this work, we focus on the jet scheme structure of three of them, called E60, E70 and E07. We construct their jet graphs and toric embedded resolution. The study di ers from the existing results in the literature as it is about the case of non-isolated hypersurfaces and surface which is not monomial neither determinantal variety.
