New results on nil rings

Abstract

For every field~Bbbk, we construct a non-nilpotent nil algebra~A whose Lie algebra A(−) is generated by ten elements. For Bbbk = ℤp, its adjoint group can also be generated by ten elements. Moreover, for every field Bbbk algebraic over its prime subfield, we construct a finitely presented algebra B over Bbbk whose Jacobson radical is not nil. These results were found with the assistance of Aristotle (Harmonic).

AB  - For every field~Bbbk, we construct a non-nilpotent nil algebra~A whose Lie algebra A^(−) is generated by ten elements. For Bbbk = ℤ_p, its adjoint group can also be generated by ten elements. Moreover, for every field Bbbk algebraic over its prime subfield, we construct a finitely presented algebra B over Bbbk whose Jacobson radical is not nil. These results were found with the assistance of Aristotle (Harmonic).
