Scheme obtained by gluing two other schemes#
- class sage.schemes.generic.glue.GluedScheme(f, g, check=True)#
Bases:
Scheme
INPUT:
f
- open immersion from a scheme U to a scheme Xg
- open immersion from U to a scheme Y
OUTPUT: The scheme obtained by gluing X and Y along the open set U.
Note
Checking that \(f\) and \(g\) are open immersions is not implemented.
