I am very pleased to announce the publication of my new book written together with Nic Fillion, "Perturbation Methods Using Backward Error", which uses Maple heavily throughout.

You can find it at

the SIAM bookstore

and I hope that you find it useful and interesting.

You can also find a paper in Maple Transactions, written with Michelle Hatzel, that explains how we generated the image that was chosen for the cover.  Exploring Cover Designs for an Upcoming Book  In the end, the SIAM design people chose a different one than we had thought, but they did pick one of the ones we generated!  

This was fun to do.

I am very pleased to announce that Volume 6 Number 1 of Maple Transactions has been published.  This is a Special Issue on Matrices and Polynomials in Computer Algebra, and the Guest Editors (our first ever!) were Marc Moreno Maza and Tomas Recio.  There are still some papers that are expected to be added to the issue when they come in, but at this moment there are 8 papers there for you to read (and a description of the issue in the Front Matter section, by the Guest Editors).

As I have stated "a few times" here on Maple Primes, I've written a new book with Nic Fillion on perturbation methods.  The book will be published by SIAM early next year.  To help market the book, I sent several images to my editor who asked her team to make a desk calendar out of them.  The PDF for that is

I had fun making the images, in Maple, and the QR code on the calendar links to a Maple Transactions paper that describes each of the images.  To save you struggling with your QR code reader, here is a link to that paper.

Best wishes for the season and for 2026.

The Autumn Issue is now up, at mapletransactions.org

This issue contains two Featured Contributions; a short but very interesting one by Gilbert Labelle on a topic very dear to my own heart, and a longer and also very interesting one by Wadim Zudilin.  I asked Doron Zeilberger about Wadim's paper, and he said "this is a true gem with lots of insight and making connections between different approaches."

The "Editor's Corner" paper is a little different, this time.  This paper is largely the work of my co-author, Michelle Hatzel, extracted and revised from her Masters' thesis which she defended successfully this past August.  I hope that you find it as interesting as I did.

We have three refereed contributions, a contribution on the use of Maple Learn in teaching, and a little note on my design of the 2026 Calendar for my upcoming SIAM book with Nic Fillion, as well.  All the images for the calendar were generated in Maple (as were most of the images in the book).

It's been fun to put this issue together (with an enormous amount of help from Michelle) and I hope that you enjoy reading it.

I would also like to thank the Associate Editors who handled the refereeing: Dhavide Aruliah, David Jeffrey, and Viktor Levandovskyy.

The Summer Issue of Maple Transactions has been published.  There are articles from a range of interests: research, education, and personal stories.

Have a look, and I hope you find something of value in the issue.
