Each undergraduate course of algebra begins with basic notions and
results concerning groups, rings, modules and linear algebra. That is,
it begins with simple notions and simple results. Our intention was to
provide a collection of exercises which cover only the easy part of ring
theory, what we have named the "Basics of Ring Theory". This seems to be
the part each student or beginner in ring theory (or even algebra)
should know - but surely trying to solve as many of these exercises as
possible independently. As difficult (or impossible) as this may seem,
we have made every effort to avoid modules, lattices and field
extensions in this collection and to remain in the ring area as much as
possible. A brief look at the bibliography obviously shows that we don't
claim much originality (one could name this the folklore of ring theory)
for the statements of the exercises we have chosen (but this was a
difficult task: indeed, the 28 titles contain approximatively 15.000
problems and our collection contains only 346). The real value of our
book is the part which contains all the solutions of these exercises. We
have tried to draw up these solutions as detailed as possible, so that
each beginner can progress without skilled help. The book is divided in
two parts each consisting of seventeen chapters, the first part
containing the exercises and the second part the solutions.
