Abstract: | We discuss the question, whether each automorphism group (of cardinality at most) of a linear order is embeddable into the automorphism group of the real line. We show that the answer to this question is independent of the axioms of ZFC: the answer is positive, if we assume< and Souslin's hypothesis; the answer is negative, if we assume orV=L. |
