D.5.2.38 tdTerms
Procedure from library chern.lib (see chern_lib).
- Usage:
- tdTerms(n, f); n integer, f polynomial
- Return:
- list of polynomials
- Purpose:
- computes the terms of the Todd class of the line bundle with the Chern root f
- Note:
Example:
| LIB "chern.lib";
ring r=0, (t), ls;;
// the terms of the Todd class of a line bundle with Chern root t up to degree 4
print( tdTerms(4, t) );
==> [1]:
==> 1
==> [2]:
==> 1/2t
==> [3]:
==> 1/12t2
==> [4]:
==> 0
==> [5]:
==> -1/720t4
