## An Invitation to General Algebra and Universal Constructions

### George M. Bergman

551 pp.

Here is the PDF file for the
notes from which Berkeley's Math 245A, "General Theory of
Algebraic Structures", is taught.
(In looking at this, you might occasionally catch it at a moment
when it is being revised, and something has gone wrong.
If that happens, look at the
next-to-last version.)
If you have any corrections or comments, you can e-mail me:

A version published with Springer's Universitext series is
expected to appear on February 14, 2015, with
ISBN 978-3-319-11477-4.

I maintain lists of answers to some questions submitted by students
over the course of the semester.
Here is the list from
Spring 2014, and here is a similar list from
Spring 2008 and Fall 2011.
The pagination has changed from year to year as I revise the material.
When I have some time, I hope to fuse these files, and give
page-references matching the published version.
