Whittaker modules for the affine Lie algebra A_1 ^{(1)}

Monday June 6th, 2016 leo 0

We prove the irreducibility of the universal non-degenerate Whittaker modules for the affine Lie algebra of type  with noncritical level. These modules can become simple Whittaker modules over with the same Whittaker function and central charge. We have to modulo a central character for sl2sl2 to obtain simple degenerate Whittaker […]
