Abstract
Let be an exceptional simple algebraic group over a field , and let be a projective -homogeneous variety such that splits over . We classify such varieties . This classification allows us to relate the Rost invariant of groups of type and their isotropy and to give a two-line proof of the triviality of the kernel of the Rost invariant for such groups. Apart from this, it plays a crucial role in the solution of a problem posed by Serre for groups of type
