We define and compare, by model-theoretical methods, some exponentiations over the quantum algebra U q (sl 2 (ℂ)). We discuss two cases, according to whether the parameter q is a root of unity. We show that the universal enveloping algebra of sl 2 (ℂ) embeds in a non-principal ultraproduct of U q (sl 2 (ℂ)), where q varies over the primitive roots of unity.
