In mathematics, blowing up or blowup is a type of geometric transformation which replaces a subspace of a given space with all the directions pointing out of that subspace. For example, the blowup of a point in a plane replaces the point with the projectivized tangent space at that point. The metaphor is that of … See more The simplest case of a blowup is the blowup of a point in a plane. Most of the general features of blowing up can be seen in this example. The blowup has a synthetic description as an incidence … See more Let Z be the origin in n-dimensional complex space, C . That is, Z is the point where the n coordinate functions $${\displaystyle x_{1},\ldots ,x_{n}}$$ simultaneously vanish. Let P be (n - 1)-dimensional complex projective space with homogeneous … See more To pursue blow-up in its greatest generality, let X be a scheme, and let $${\displaystyle {\mathcal {I}}}$$ be a coherent sheaf of ideals on X. The blow-up of X with respect to $${\displaystyle {\mathcal {I}}}$$ is a scheme See more More generally, one can blow up any codimension-k complex submanifold Z of C . Suppose that Z is the locus of the equations $${\displaystyle x_{1}=\cdots =x_{k}=0}$$, and let $${\displaystyle y_{1},\ldots ,y_{k}}$$ be homogeneous coordinates on P . … See more In the blow-up of C described above, there was nothing essential about the use of complex numbers; blow-ups can be performed over any See more • Infinitely near point • Resolution of singularities See more
