D.15.4.41 chProj

Procedure from library chern.lib (see chern_lib).

Usage:
chProj(n); n integer

Return:
list of (rational) numbers

Purpose:
computes the terms of the Chern character of the tangent bundle on the complex projective space

Note:

Example:
 
LIB "chern.lib";
ring r=0, (t), dp;
// the coefficients of the Chern character of the complex projective line
print( chProj(1) );
==> [1]:
==> 1
==> [2]:
==> 2
// the coefficients of the Chern character of the complex projective plane
print( chProj(2) );
==> [1]:
==> 2
==> [2]:
==> 3
==> [3]:
==> 3/2
// the coefficients of the Chern character of the complex 3-dimentional projectice space
print( chProj(3) );
==> [1]:
==> 3
==> [2]:
==> 4
==> [3]:
==> 2
==> [4]:
==> 2/3
