D.10.1.2 NSplaces
Procedure from library brnoeth.lib (see brnoeth_lib).
- Usage:
- NSplaces( h, CURVE ), where h is an intvec and CURVE is a list
- Return:
- list L with updated data of CURVE after computing all non-singular
affine closed places whose degrees are in the intvec h:
| in L[1][1]: (affine ring) lists Aff_Points(d) with affine non-singular
(closed) points of degree d (if non-empty),
in L[3]: the newly computed closed places are added,
in L[5]: local rings created/updated to store (repres. of) new places.
| See Adj_div for a description of the entries in L.
- Note:
- The list_expression should be the output of the procedure Adj_div.
Raising printlevel , additional comments are displayed
(default: printlevel=0 ).
- Warning:
- The parameter of the needed field extensions is called 'a'. Thus,
there should be no global object named 'a' when executing NSplaces.
Example:
