Irreducible polynomials from a cubic transformation
Sandro Mattarei, Marco Pizzato
Let be a rational expression of degree three over the finite field . We count the irreducible polynomials in , of a given degree, wh…
The earliest diamond of finite type in Nottingham algebras
Marina Avitabile, Sandro Mattarei
We prove several structural results on Nottingham algebras, a class of infinite-dimensional, modular, graded Lie algebras, which includes the graded Lie algebra associated to the N…
Cubic rational expressions over a finite field
Sandro Mattarei, Marco Pizzato
We study and partially classify cubic rational expressions over a finite field , up to pre- and post-composition with independent Möbius transformations.…
A sandwich in thin Lie algebras
Sandro Mattarei
A thin Lie algebras is a Lie algebra , graded over the positive integers, with its first homogeneous component of dimension two and generating , and such that each nonz…
