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 […]
