Procedure from librarychern.lib (see chern_lib).
- Usage:
- tdProj(n); n integer
- Return:
- list of (rational) numbers
- Purpose:
- computes the terms of the Todd class
of the (tangent bundle of the) complex projective space - Note:
LIB "chern.lib"; ring r=0, (t), dp; // the coefficients of the Todd class of the complex projective line print( tdProj(1) ); // the coefficients of the Todd class of the complex projective line print( tdProj(2) ); // the coefficients of the Todd class of the complex projective line print( tdProj(3) ); |
