D.5.2.38 tdTerms
Procedure from librarychern.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:
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 |
