Evolution algebras, automorphisms, and graphs
Resumen: The affine group scheme of automorphisms of an evolution algebra e with e 2 is shown to lie in an exact sequence ¿ D ¿ Aut(E) ¿ S, where D, diagonalizable, and S, constant, depend solely on the directed graph associated to e. As a consequence, the Lie algebra of derivations Der(e) (with e 2 = E)is shown to be trivial if the characteristic of the ground field is 0 or 2, and to be abelian, with a precise description, otherwise.
