D.15.3.42 chNumbersProj
Procedure from librarychern.lib (see chern_lib).
- Usage:
- chNumbersProj(n); n integer
- Return:
- list of integers
- Purpose:
- computes the Chern numbers of the projective space P_n
- Note:
LIB "chern.lib"; ring h=0, (t), dp; // The Chern numbers of the projective plane P_2: print( chNumbersProj(2) ); ==> [1]: ==> 9 ==> [2]: ==> 3 // The Chern numbers of P_3: print( chNumbersProj(3) ); ==> [1]: ==> 64 ==> [2]: ==> 24 ==> [3]: ==> 4 |
