From octonions to composition superalgebras via tensor categories
(European Mathematical Society, 2024)
The nontrivial unital composition superalgebras, of dimension 3 and 6, which exist only in characteristic 3, are obtained from the split Cayley algebra and its order 3 automorphisms, by means of the process of semisimplification ...

Parallel homological calculus for 3D binary digital images
(Springer, 2024-01-29)
Topological representations of binary digital images usually take into consideration different adjacency types between colors.Within the cubical-voxel 3D binary image context, we design an algorithm for computing the ...

Cross products, automorphisms, and gradings
(Elsevier, 2021-02-01)
The affine group schemes of automorphisms of the multilinear rfold cross products on finite-dimensional vectors spaces over fields of characteristic not two are determined. Gradings by abelian groups on these structures, ...
