Kac-Moody algebras from M5-giants
Abstract
A bstract We examine the giant graviton expansions of the Higgs indices for the 3d π© = 4 U ( N ) ADHM theories with l fundamental hypermultiplets. The indices for the M5-brane giant gravitons of wrapping number m appearing in the expansions consist of the contributions that generalize the characters of the W-algebra π²(π€π©( m )) and those which realize the characters of the affine Kac-Moody algebras of type A l β1 . Also we confirm that the inverse giant graviton expansions of the resulting M5-brane indices consistently reproduce the Higgs indices.
