Abstract
We compare three different characterizations, due respectively to R. Dedekind, K. Uchida, and H. Lüneburg, of when, given an algebraic integer, the ring generated by it coincides with the ring of integers of its quotient field, and apply our results to some concrete 2-towers of number fields.
