Automorphism group schemes of Kantor pairs of associative central simple structurable algebras
Diego Aranda-Orna, Alejandra S. Córdova-Martínez, Alberto Daza-García
In this work, a description of the automorphism group schemes is given for the Kantor pairs (and for some Kantor triple systems related to them) associated to associative central s…

Fine gradings on Kantor systems of Hurwitz type
Diego Aranda-Orna, Alejandra S. Córdova-Martínez
We give a classification up to equivalence of the fine group gradings by abelian groups on the Kantor pairs and triple systems associated to Hurwitz algebras (i.e., unital composit…

Gradings on tensor products of composition algebras and on the Smirnov algebra
Diego Aranda-Orna, Alejandra S. Córdova-Martínez
We give classifications of group gradings, up to equivalence and up to isomorphism, on the tensor product of a Cayley algebra and a Hurwitz algebra over a field of ch…
