The coordinate ring of the k-fold iterated commutator locus for 2x2 matrices

Jan Snellman

For $2 \times 2$ matrices $A_{1}, \dots, A_{k}$ , write $[A_{1}, \dots, A_{k}]$ for the left-normed iterated commutator $[\dots [[A_{1}, A_{2}], A_{3}], \dots, A_{k}]$ , and $I_{k}$ for the ideal, in the $3 k$ -…

Truncations of the ring of number-theoretic functions, revisited

Jan Snellman

Let $K$ be a field containing $Q$ , let $Γ$ be the ring of all functions from the positive integers to $K$ under Dirichlet convolution, and let $Γ_{n}$ be its truncation to f…

Infinite Minkowski sums of lattice polyhedra

Jan Snellman

Artinian integrally closed monomial ideals are characterized by their Newton polyhedra, which are lattice polyhedra inside the positive orthant having the positive orthant as their…

The ring of arithmetical functions with unitary convolution: the [n]-truncation

Jan Snellman

We study a certain truncation of the ring of arithmetical functions with unitary convolution, consisting of functions vanishing on arguments >n. The truncations are artinian monomi…

The ring of arithmetical functions with unitary convolution: General Truncations

Jan Snellman

Let A denote the ring of arithmetical functions with unitary convolution, and let V be a finite subset of the positive integers having the property that for every v in V, all unita…

The ring of arithmetical functions with unitary convolution: Divisorial and topological properties

Jan Snellman

We study the ring of arithmetical functions with unitary convolution, giving an isomorphism to a generalized power series ring on infinitely many variables, similar to the isomorph…
