|  |  D.15.16.6 BettiNumsQp Procedure from librarygoettsche.lib(see  goettsche_lib).
 
Example:Usage:
BettiNumsQp(r, n); n, r integers
Return:
list of non-negative integers
Purpose:
computes the Betti numbers of the punctual Quot-scheme
of rank r on n points on a plane
Note:
an empty list is returned if n<0 or r<=0
 |  | LIB "goettsche.lib";
ring r=0, (z), ls;
// get the Betti numbers of the punctual Hilbert scheme (r=1)
// of 3 points on a plane
print( BettiNumsQp(1, 3) );
