Abstract

We study the existence of generalized complex structures on the six-dimensional sphere S6\mathbb S^6. We work with the generalized tangent bundle TS6S6\mathbb T\mathbb S^6\to \mathbb S^6 and define the integrability of generalized geometric structures in terms of the Dorfman bracket. Specifically, we prove that there is not a direct way to induce a generalized complex structure on S6\mathbb S^6 from its usual nearly K\"ahler structure inherited from the octonions product.
