Please be aware that this textbook is still a work in progress! While enough of the book is written to cover a typical introductory pure mathematics course, I am currently working on additional sections that allow instructors more flexibility in what topics to cover. There are also portions of the book that I would like to edit substantially.
Any feedback, be it from students, teaching assistants, instructors or any other readers, would be very much appreciated. Particularly useful are corrections of typographical errors, suggestions for alternative ways to describe concepts or prove theorems, and requests for new content (e.g. if you know of a nice example that illustrates a concept, or if there is a relevant concept you wish were included in the book).
