`desing/blowup`

Performing blowing up operation on a chart-record along a given center. The center is defined as the intersection of hypersurfaces defined by elements from IND. The procedure creates new chart-records whose charts cover the blown up variety and the basic objects are transformed properly along the stack.

Input:

 

O

a chart-record,

C

a list of pairwise different indices to the IND member of the chart of the chart-record,

gp

boolean, true if the transformation is a "goodpoint" blowing up, false in the generic case.

Output:

a list of chart-records covering the blowing up variety.
