On the Cachazo-Douglas-Seiberg-Witten conjecture for simple Lie algebras, II

Abstract

Recently, motivated by supersymmetric gauge theory, Cachazo, Douglas, Seiberg, and Witten proposed a conjecture about finite dimensional simple Lie algebras, and checked it in the classical cases. Later V. Kac and the author proposed a uniform approach to this conjecture, based on the theory of abelian ideals in the Borel subalgebra; this allowed them to check the conjecture for type G_2. In this note we further develop this approach, and propose three natural conjectures which imply the three parts of the CDSW conjecture. In a sense, these conjectures explain why the CDSW conjecture should be true. We show that our conjectures hold for classical Lie algebras and for G_2; this, in particular, gives a purely algebraic proof of the CDSW conjecture for SO(N) (the original proof, due to Witten, uses the theory of instantons).
