A recent answer motivated me to post about this. I've always had a vague, unpleasant feeling that somehow lattice theory has been completely robbed of the important place it deserves in mathematics - lattices seem to show up everywhere, the author or teacher says "observe that these ____ form a complete lattice" or something similar, and then moves on, never to speak of what that might imply. But, not currently knowing anything about them, I can't be sure. What would be a good place to learn about lattice theory, especially its implications for "naturally occurring" lattices (subgroups, ideals, etc.)?

A good, user-friendly, modern, introductory textbook is Davey and Priestley's Introduction to Lattices and Order.

Incidentally, Gian-Carlo Rota used to say much the same thing as you, Zev: that lattice theory had been robbed of its rightful place in mathematics.

Thanks for the recommendation! Also, I think I may have heard Rota's quote somewhere, but couldn't remember its correct attribution, or whether it was a quote, etc., hence the similar phrasing. – Zev Chonoles Feb 6 at 1:42

I second this recommendation. I was just looking through this book again a few days ago and reminded how very nice it is. – Steve D Feb 6 at 1:47

If you haven't already read Rota's Notices article, here's a link to it: ams.org/notices/199711/comm-rota.pdf – jc Feb 6 at 2:15

Good link, jc. How's this for an opening sentence? "Never in the history of mathematics has a mathematical theory been the object of such vociferous vituperation as lattice theory." Rota could certainly grab your attention. – Tom Leinster Feb 6 at 2:39

I had the good fortune to learn lattice theory from Priestley herself and completely concur with the sentiment that there is so much more to lattice theory than is commonly thought. The book is very readable and extremely interesting. I recommend it highly. – Andrew Stacey Feb 6 at 20:08

George Grätzer has written a couple of well-regarded books on lattices. The wikipedia page recommends his "Lattice theory. First concepts and distributive lattices" and several others.

G. Gratzer's "General Lattice Theory" is a really thorough monograph. (Beware: it's over 600 pages long!). – Michał Kukieła Mar 12 at 16:15

Searching online I found a couple of books:

Roman - Lattices and Ordered Sets
Blyth - Lattices and Ordered Algebraic Structures

and a set of lecture notes, available for free from the author's webpage:

Nation - Notes on Lattice Theory

I've used Garret Birkhoff book "Lattice theory". Could be a bit outdated nowadays, but it gives a deep feeling. Not so sure if it is good as lattice field is not my field.

If you want to see lattice theory in action, check out a book on Universal Algebra. Graetzer wrote such a text, so I imagine (but do not know from experience) that he will have many such examples; I cut my teeth on "Algebras, Lattices, Varieties", which has a gentle introduction to lattice theory from a universal algebraic point of view, followed by many universal algebraic results depending on that introduction. This was co-written by my advisor, Ralph McKenzie.

(Hopefully others will share examples from other fields that use lattices.)

Good lattice theory books?
