On the Kernel of the Affine Dirac Operator
Let g be a finite-dimensional semisimple Lie algebra and (• , •) its Killing form, σ an elliptic automorphism of g, and a a σ-invariant reductive subalgebra of g, such that the restriction of the form (• , •) to a is non-degenerate.Let L(g, σ) and L(a, σ) be the …
