    I added a clearer “The idea” section for Adams operation, and changed the word “functorial” to “natural” in a number of places, because while various sources do say the Adams operations are functorial, they must really be natural transformations from the functor K:Top→AbGpK: Top \to AbGp to itself.

    added statement of the compatibility of the Adams operations with the Chern character (here).

    Will also give this its own page Adams operations compatible with the Chern character, for ease of cross-linking and referencing.

    added brief statement (here) of the action of the Adams operations over 2n2n-spheres (without the proof, but with a pointer to a proof)

    Gave a proof that the kth Adams operation, applied to the K-theory class of a line bundle, gives the class of the kth tensor power of that line bundle.
