%0 Journal Article %A Bazzoni, Giovanni %A Muñoz, Vicente %T Classification of minimal algebras over any field up to dimension 6. %D 2012 %@ 0002-9947 %U https://hdl.handle.net/20.500.14352/42375 %X We give a classification of minimal algebras generated in degree 1, defined over any field k of characteristic different from 2, up to dimension 6. This recovers the classification of nilpotent Lie algebras over k up to dimension 6. In the case of a field k of characteristic zero, we obtain the classification of nilmanifolds of dimension less than or equal to 6, up to k-homotopy type. Finally, we determine which rational homotopy types of such nilmanifolds carry a symplectic structure. %~
