D.5.12.2 Eresol
Procedure from library resbinomial.lib (see resbinomial_lib).
- Usage:
- Eresol(J); J ideal
- Return:
- The E-resolution of singularities of J in terms of the affine charts, see example
Example:
| | LIB "resbinomial.lib";
ring r = 0,(x(1..2)),dp;
ideal J=x(1)^2-x(2)^3;
list L=Eresol(J);
"Please press return after each break point to see the next element of the output list";
==> Please press return after each break point to see the next element of the\
output list
L[1][1]; // information of the first chart, L[1] list of charts
