On the brane expansion of the Schur index

Journal of High Energy Physics, 2023
We consider the Schur index of N $$ \mathcal{N} $$ = 4 U(N) SYM theory in 4d and its holographic giant graviton-type expansion at finite N. We compute the world-volume brane superconformal index by a recently proposed definition of the gauge holonomy ...

Orbifold Schur Index and IR formula

Progress of Theoretical and Experimental Physics, 2018
We discuss orbifold version of the Schur index defined as the supersymmetric partition function in S^3/Z_n x S^1. We first give a general formula for Lagrangian theories obtained by localization technique, and then suggest a generalization of the Cordova

Macdonald index and chiral algebra

Journal of High Energy Physics, 2017
For any 4d N $$ \mathcal{N} $$ = 2 SCFT, there is a subsector described by a 2d chiral algebra. The vacuum character of the chiral algebra reproduces the Schur index of the corresponding 4d theory.

Surface defect indices and 2d-4d BPS states

Journal of High Energy Physics, 2017
We conjecture a formula for the Schur index of four-dimensional N=2 $$ \mathcal{N}=2 $$ theories coupled to (2, 2) surface defects in terms of the 2d-4d BPS spectrum in the Coulomb phase of the theory. The key ingredient in our conjecture is a refined 2d-

On the chiral algebra of Argyres-Douglas theories and S-duality

Journal of High Energy Physics, 2018
We study the two-dimensional chiral algebra associated with the simplest Argyres-Douglas type theory with an exactly marginal coupling, i.e., the (A 3 , A 3) theory.

Vertex operator algebras of Argyres-Douglas theories from M5-branes

Journal of High Energy Physics, 2017
We study aspects of the vertex operator algebra (VOA) corresponding to Argyres-Douglas (AD) theories engineered using the 6d N=2,0 $$ \mathcal{N}=\left(2,\ 0\right) $$ theory of type J on a punctured sphere.

Using character correspondences for Schur index computations

Journal of Algebra, 2003
A new method of computing the Schur index associated with an irreducible complex character of a finite group over the field \(\mathbb{Q}\) of rational numbers is presented. This method uses the Isaacs-Dade character correspondence to reduce to a subgroup of the original group.

Using G-algebras for Schur index computation

Journal of Algebra, 2003
The paper under review is concerned with the problem of computing the Schur index \(m_K(\chi)\) of an irreducible character \(\chi\) of a finite group \(G\) over an algebraic number field \(K\). The author uses the theory of central simple \(G\)-algebras as developed by \textit{A.~Turull} [J. Algebra 170, No.

Giant graviton expansion of Schur index and quasimodular forms

Journal of High Energy Physics
The flavored superconformal Schur index of N $$ \mathcal{N} $$ = 4 U(N) SYM has finite N corrections encoded in its giant graviton expansion in terms of D3 branes wrapped in AdS 5 × S 5.
