• Resumen

  • The techniques and concepts we present are flags of regular schemes and their persistence under blow-up, the Gauss¿Bruhat decomposition of the group of formal automorphisms of affine space, and coordinate-free initial ideals. All three are used to construct and study invariants for resolution of singularities.
