DAC notes

I plan to write some notes on dynamical algebraic combinatorics (perhaps to one day be converted into a book). You can see the tentative outline here.

Research papers

Open access journals in combinatorics

There are several online, open access journals in combinatorics. I especially like:

The latter two are supported by The Combinatorics Consortium. Some other good open access journals in combinatorics (and related areas) include: Consider submitting your combinatorics paper to one of these open access journals.
