Relations on a lattice of varieties of completely regular semigroups [PDF]

Mathematica Bohemica, 2020
Completely regular semigroups $\mathcal{CR}$ are considered here with the unary operation of inversion within the maximal subgroups of the semigroup. This makes $\mathcal{CR}$ a variety; its lattice of subvarieties is denoted by $\mathcal{L(CR)}$.

Affine Subspace Concentration Conditions [PDF]

Épijournal de Géométrie Algébrique, 2023
We define a new notion of affine subspace concentration conditions for lattice polytopes, and prove that they hold for smooth and reflexive polytopes with barycenter at the origin.
