On algebraic endomorphisms of the Einstein gyrogroup

Abstract

We describe the structure of all continuous algebraic endomorphisms of the open unit ball B\mathbf{B} of R3\mathbb{R}^3 equipped with the Einstein velocity addition. We show that any nonzero such transformation originates from an orthogonal linear transformation on R3\mathbb{R}^3.
