of an analytic space
An analytic mapping 
of analytic spaces such that for certain analytic sets 
and 
of smaller dimensions, the conditions
 |
and
 |
hold. A modification is also called a contraction of 
onto 
. An example of a modification is a monoidal transformation.
See also Exceptional analytic set; Exceptional subvariety.
