Macdonald Index From Refined Kontsevich-Soibelman Operator
George Andrews, Anindya Banerjee, Ranveer Kumar Singh +1
We propose a refinement of the Kontsevich-Soibelman operator for a class of ``special'' 4d superconformal field theories characterized by the following conditions:…
Path Integral Derivations Of K-Theoretic Donaldson Invariants
Heeyeon Kim, Jan Manschot, Gregory W. Moore +2
We consider 5d SU(2) super Yang-Mills theory on , with a closed smooth four-manifold. A partial topological twisting along renders the theory f…
Argyres-Douglas Theories, Macdonald Indices and Arc Space of Zhu Algebra
George Andrews, Anindya Banerjee, Chinmaya Bhargava +2
In this paper, we relate the MacDonald index of a 4d SCFT with the Hilbert series of the arc space of the Zhu algebra of the corresponding Schur VOA. Using this, we…
Rationality of Lorentzian Lattice CFTs And The Associated Modular Tensor Category
Ranveer Kumar Singh, Madhav Sinha, Runkai Tao
We classify the irreducible modules of a rational Lorentzian lattice vertex operator algebra (LLVOA) based on an even, self-dual Lorentzian lattice of s…
