A tiny note on Gauss's lemma
The author's abstract states: ``Gauss' lemma is a theorem on transfers.'' This refers to the lemma of Gauss used in the proof of the quadratic reciprocity law. The author states a group theoretic generalization of Gauss' lemma and shows that the proof uses the homomorphism law as the transfer. The interested reader is referred to \textit{A. Leutbecher} [Arch. Math. 23, 151-153 (1972; Zbl 0251.10003)] for a more technical discussion of this relationship.
