We introduce the notion of the full quiver of a representation of an algebra,
which is a cover of the (classical) quiver, but which captures properties of
the representation itself. Gluing of vertices and of arrows enables one to
study subtle combinatorial aspects of algebras which are lost in the classical
quiver. Full quivers of representations apply especially well to \Zcd\
algebras, which have properties very like those of finite dimensional algebras
over fields. By choosing the representation appropriately, one can restrict the
gluing to two main types: {\it Frobenius} (along the diagonal) and, more
generally {\it proportional} Frobenius gluing (above the diagonal), and our
main result is that any representable algebra has a faithful representation
described completely by such a full quiver. Further reductions are considered,
which bear on the polynomial identities.Comment: 44 p
