D.15.3.40 cProj

Procedure from library chern.lib (see chern_lib).

Usage:
cProj(n); n integer

Return:
list of integers

Purpose:
computes the terms of positive degree of the total Chern class of the tangent bundle on the complex projective space

Note:

Example:
 
LIB "chern.lib";
ring r=0, (t), dp;
// the coefficients of the total Chern class of the complex projective line
print( cProj(1) );
==> [1]:
==>    2
// the coefficients of the total Chern class of the complex projective line
print( cProj(2) );
==> [1]:
==>    3
==> [2]:
==>    3
// the coefficients of the total Chern class of the complex projective line
print( cProj(3) );
==> [1]:
==>    4
==> [2]:
==>    6
==> [3]:
==>    4
