The orders of nonsingular derivations of Lie algebras of characteristic two
Sandro Mattarei
Nonsingular derivations of modular Lie algebras which have finite multiplicative order play a role in the coclass theory for pro- groups and Lie algebras. A study of the set N_p…

Diamonds of finite type in thin Lie algebras
Sandro Mattarei, Marina Avitabile
Borrowing some terminology from pro-p groups, thin Lie algebras are N-graded Lie algebras of width two and obliquity zero, generated in degree one. In particular, their homogeneous…

Gradings of non-graded Hamiltonian Lie algebras
Andrea Caranti, Sandro Mattarei
A thin Lie algebra is a Lie algebra graded over the positive integers satisfying a certain narrowness condition. We describe several cyclic grading of the modular Hamiltonian Lie a…
