Resumo

For each two-dimensional vector space V of commuting n x n matrices over a field IF with at least 3 elements, we denote by V the vector space of all (n + 1) x (n + 1) matrices of the form {[}A 0 {*} 0] with A is an element of V. We prove the wildness of o the problem of classifying Lie algebras (V) over tilde with the bracket operation {[}u, v] := uv - vu. We also prove the wildness of the problem of classifying two-dimensional vector spaces consisting of commuting linear operators on a vector space over a field. (C) 2017 Elsevier Inc.
