Ternary mappings of some evolution algebras

Abstract

The group scheme of ternary automorphisms of a perfect finite dimensional evolution algebra is computed. The main advantage of using group schemes is that it allows to apply the Lie functor to determine the Lie algebra of ternary derivations of A. Using the generalised inverse of a matrix, we provide a precise classification of all ternary derivations of an arbitrary finite-dimensional evolution algebra . The ternary derivations of all 2-dimensional evolution algebras are also computed.
