Radicals in primitive axial algebras

Rings and Algebras 2026-02-13 v1

Abstract

The paper contributes to the structure theory of primitive axial algebras. For a primitive axial algebra AA with a Frobenius form we compare the largest ideal R(A)R(A) not containing any of the generating axes, the radical AA^\perp of the form, and the Jacobson radical J(A)J(A), which we define simply as the intersection of all maximal ideals of AA.
