The Grimoire Project

The Grimoire is a textbook on commutative algebra for advanced master students and graduate students, that I started writing in early 2014, and completed in January 2022. Some of its last chapters could be interesting also to more advanced researchers. It is written in French. Here you can freely download the complete and final text :

  • Grimoire d'Algèbre Commutative

  • Your comments are welcome and gratefully acknowledged!

  • The Blog of the Grimoire Project documented the project from its beginning in 2014 all the way to its conclusion in January 2022.


  • UPDATE June 2025 : An unfortunate news concerning the shipping rates for the Grimoire : until now, for destinations outside of France, we used a special shipping option (the so-called "tariffe livres et brochures") reserved for sending abroad cultural material written in french. This tariff was created 22 years ago by the french postal service, as a means to encourage the spread of french culture in the world. Unfortunately, in the last several years, priorities have been shifting, and early this year the french postal service has announced that this tariff will be discontinued in July. This leaves countless of small french independent publishers and self-publishing authors without a good option for shipping their works to non-french audiences. Indeed, the alternatives are much more expensive : as a result of these changes, the cost of shipping the Grimoire outside France will rise sharply, starting from July : for european destinations it will be around 25 Euros, and for other destinations it should be probably around 35 Euros. So, if you are a resident of a non-european country, you might want to find some friend who lives in Europe (or better, in France), have the book shipped to them, and ask them to bring it over to you on their next trip! (Just a suggestion)

    UPDATE June 2023 : The second printing of the Grimoire is here! It has taken a little more than one year to reach this milestone! The price of the second printing is the same as for the first printing; the second printing corrects all the misprints that have been pointed out by our eagle-eyed readers. The paper is slightly different : whereas the grammage of the first printing was 50gr/m^2, for the second printing I've tried 60gr/m^2 : this means that the volume is about 200gr heavier, and also 7mm thicker. Apart from that, it is still the same friendly satanic volume!

    As of April 12, 2022, the Grimoire is available in print. In March 2022 I have created the Publishing House Les Presses Insoumises to publish and distribute the paper version of the Grimoire. Here is the website :

  • Les Presses Insoumises

  • From the publisher's website you can buy the book for 50 Euros plus shipping expenses : we ship all over the world! The payment is via credit card, just like you would do on Amazon. If you're interested in such things, the credit card securized transaction is handled via Stripe.

    By the way : if you think this project is useful, one easy way to support it, is by asking your local math library to buy one (or more) copies.

    The book can also be ordered from several french bookstores; here is a sample :
  • Librairie Eyrolles (Paris)
  • Librairie Decitre (Lyon)
  • Librairie Unitheque (Tours)

  • And apparently, you can even buy it from Tokyo's Kinokuniya's bookstore!

    Though, if you live in Paris you can also contact me directly, and then I can meet you somewhere to hand you a copy : in this way you avoid the shipping expenses.
