Talk:Abstract Algebra/Modules

Submodule Def'n
There was a second defn for submodule suggested. Really, both definitions were the same, but the second one expressed the idea better by enumerating the conditions. I've merged these two. Also, I've ommited that submodules must be non empty, since this is implied by their being subgroups of the containing module. Does this merit, comment in the text? Methinks not.
