Abstract [en]
Let F be a field of characteristic different from 2. It is shown that the problems of classifying
(i) local commutative associative algebras over F with zero cube radical,
(ii) Lie algebras over F with central commutator subalgebra of dimension 3, and
(iii) finite p-groups of exponent p with central commutator subgroup of order are hopeless since each of them contains
• the problem of classifying symmetric bilinear mappings UxU → V , or
• the problem of classifying skew-symmetric bilinear mappings UxU → V ,
in which U and V are vector spaces over F (consisting of p elements for p-groups (iii)) and V is 3-dimensional. The latter two problems are hopeless since they are wild; i.e., each of them contains the problem of classifying pairs of matrices over F up to similarity.
