Özet

An 8-dimensional generalization of the sigma model is given and it is shown that these fields have topological charge n and satisfy a self-duality equation for the octonionic mappings x(n): S8 --> S8. Furthermore the Euler-Poincare index I(E) and the Pontryagin index I(P) are generalized to eight dimensions and it is shown that I(E) = n, I(P) = 0 for the above mappings.
