The official, authoritative versions of PS-36-T and PS-36-NT are on the LSU website---click on Administration and then on LSU Policies & Procedures. The annotated versions, with their added footnotes, remarks, indices, and commentary, are entirely and solely the responsibility of Carruth McGehee. They are PS-36-T with Notes for Users and PS-36-NT with Notes for Users.
 

Here are links to the Table of Contents and the Preface. If you have the second or later printing of the book, please consult this list of corrections and other emendations. If you have the first printing, here is a further list of corrections. If you find further errors in the book, or if you have questions or comments, please let me hear from you. As a possible aid to teachers using the text, here is a schedule of lectures and assignments from 2002 to indicate one way in which to conduct a one-semester undergraduate course using the book as a text. Also, here is a schedule of lectures and assignments showing how I ran a summer-term course for graduate students in 2001.
 

In 1993 I had the privilege to give a lecture at a conference held at Orsay in honor of Professor Jean-Pierre Kahane. In the talk, I undertook to describe the conceptual setting of the LIttlewood Conjecture. It is deliberately sketchy but does include a proof of the main result.
 
 

On pages 5-7 of this PDF file you will find my review that appeared in the MAA Monthly. You may ignore pages 1-4, another book review that appeared in the same edition of the Monthly.
 

Here is a five-page PDF file presenting a solution algorithm for Rubik's cube. I prepared this in 1997 when teaching Mathematics 2040, a "transition course" for mathematics majors to take between the calculus sequence and the more rigorous upper-division courses in algebra and analysis. Part of the course was devoted to beginning group theory. The transformation group of Rubik's cube provided interesting examples. The process of learning how to solve the cube also offered an object lesson in the need to read and write general and somewhat abstract statements. Nearly all the students learned to solve the cube in under seven minutes.

Here is a PDF file in which the properties of the exponential function are derived from its differential equation.

Consider a system of equations representable as x' = Ax when A is an n-by-n matrix. Here is a one-page PDF file, explaining one method of finding a fundamental matrix by hand.

Here is a brief note on differential forms.
