Blowing up

Summary

• In mathematics, blowing up is a type of geometric modification, particularly applied in algebraic geometry, where it is essential in birational geometry. At a point Z that is being 'blown up' (the metaphor is inflation of a balloon, rather than explosion), Z is replaced by the whole space of tangent directions at Z (which, more formally, can be defined as the projective space constructed from the tangent space at Z).
