Abstract

A classification of all 4-dimensional absolute valued algebras with left omnipresent unit is given. We also construct, by algebraic methods some new models of 4-dimensional
absolute valued algebras with left omnipresent unit. These new algebras contain at least one 2-dimensional sub-algebra, and aren’t isomorphic to H (quaternion algebra
