Resumen: Kac’s ten-dimensional simple Jordan superalgebra over analgebraically closed field of characteristic 5 is obtained froma process of semisimplification, via tensor categories, fromthe exceptional simple Jordan algebra (or Albert algebra),together with a suitable order 5 automorphism.This explains McCrimmon’s ‘bizarre result’ asserting that,in characteristic 5, Kac’s superalgebra is a sort of ‘degree 3Jordan superalgebra’.As an outcome, the exceptional simple Lie superalgebrael(5; 5), specific of characteristic 5, is obtained from the simpleLie algebra of type E8 and an order 5 automorphism.In the process, precise recipes to obtain superalgebras fromalgebras in Rep Cp (or Rep αp), p > 2, are given Idioma: Inglés DOI: 10.1016/j.jalgebra.2024.12.006 Año: 2024 Publicado en: Journal of Algebra 666 (2024), 387-414 ISSN: 0021-8693 Financiación: info:eu-repo/grantAgreement/ES/DGA/E22-20R Financiación: info:eu-repo/grantAgreement/ES/MCINN/PID2021-123461NB-C21 Tipo y forma: Artículo (Versión definitiva) Área (Departamento): Área Algebra (Dpto.
