DESCRIPTION:It is a classical result of Hirzebruch that the quaternion projective spaces do not\nadmit any almost complex structure. In my talk I will show how the Atiyah-Singer\nindex theorem can be used to give a short alternative proof, which applies to a\nmuch larger class of manifolds. With a similar idea it is possible to decide which\ninner symmetric spaces admit almost complex structures.
