A technique in geometry (especially algebraic and differential, and, by extension, the study of pseudo-differential operators) for resolution of singularities. Not to be confused with the formation of singularities in solutions of ordinary or partial differential equations.
Blowup is a technique in geometry (especially algebraic and differential, and, by extension, the study of pseudo-differential operators) for resolution of singularities. It should not be confused with the formation of singularities in solutions of ordinary or partial differential equations.
For more information, one should consult Wikipedia on singularity resolution.
