Abstract

This is a short note on generalized G2G_2-structures obtained as a consequence of a TT-dual construction given in a previous work of the authors together with Leonardo Soriani. Given classical G2G_2-structure on certain seven dimensional manifolds, either closed or co-closed, we obtain integrable generalized G2G_2-structures which are no longer an usual one, and with non-zero three form in general. In particular we obtain manifolds admitting closed generalized G2G_2-structures not admitting closed (usual) G2G_2-structures.
