The Reverse Mathematics of Noether's Decomposition Lemma

We will survey some recent results in the Reverse Mathematics of Noetherian Algebra, and in particular Noether's Decomposition Lemma which states that a Noetherian ring has only finitely many minimal prime ideals. Such an analysis naturally leads one to formulate a combinatorial principle, namely the Tree-Antichain Principle, which states that every binary-branching tree with infinitely many splittings has an infinite antichain.
