Inverse-closed additive subgroups of fields
Sandro Mattarei
We describe the additive subgroups of fields which are closed with respect to taking inverses. In particular, in characteristic different from two any such subgroup is either a sub…

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…
