  1. A bare beginning, will fill in more later.

    v1, current

  2. Completed the second definition of a Galois category, and a remark on the choice of axioms. Will give the details of the theorem relating the two as soon as possible.

    diff, v2, current

  3. Clarified the third point in the definition of the Galois category. Previously, the entry said that there exist morphisms uu and vv, but did not say that their composite was supposed to be ff.
