Combinatorics is flourishing, at least in the lists of the European Mathematical Society publishing house.
A few years ago, I mentioned the new journal Combinatorics, Physics and their Interactions, aka Annales de l’Institut Henri Poincaré D.
Now they have announced a new journal starting up next year, Journal of Combinatorial Algebra, with Mark Sapir as editor-in-chief. The “Aims and Scope” say,
Its domain is the rich and deep interplay between combinatorics and algebra. Its scope includes combinatorial aspects of group, semigroup and ring theory, representation theory, commutative algebra, algebraic geometry and dynamical systems.
I am not completely certain how this scope differs from that of the Springer Journal of Algebraic Combinatorics, but no doubt this will become clearer in time; a journal is defined by its contents more than by its aims and scope.
It is particularly pleasing that both these journals are specifically about combinatorics and something else. This is combinatorics doing the job it grew up to do, in my opinion.
And also, of course, the first issue of the EMS Surveys in Mathematical Sciences in 2014 was devoted to a survey article by Terence Tao on “Algebraic combinatorial geometry”.
