D.15.3.40 tdProj

Procedure from library chern.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:

Example:
 
LIB "chern.lib";
ring r=0, (t), dp;
// the coefficients of the Todd class of the complex projective line
print( tdProj(1) );
==> [1]:
==>    1
==> [2]:
==>    1
// the coefficients of the Todd class of the complex projective line
print( tdProj(2) );
==> [1]:
==>    1
==> [2]:
==>    3/2
==> [3]:
==>    1
// the coefficients of the Todd class of the complex projective line
print( tdProj(3) );
==> [1]:
==>    1
==> [2]:
==>    2
