Abstract

We compute the filling radius with rational coefficients of CPn by studying the Serre spectral sequence of the total space of the unit tangent bundle viewed as a principal SO(3)-bundle on the Grassmannian of 2-planes in CPn. We also compute the (integer) filling radius of CPn and exhibit a torsion obstruction to filling CPn. We discuss a related aspect of the global geometry of CPn.
