| #### D.5.2.41 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) );
    // the coefficients of the Chern character of the complex projective plane
    print( chProj(2) );
    // the coefficients of the Chern character of the complex 3-dimensional projective space
    print( chProj(3) );
