-algebras
Davide Gaiotto
We introduce the notion of -algebra, a conjectural axiomatization of the fusion algebra of rotation-equivariant BPS line defects in a 4d Supersymmetr…
Interface Minimal Model Holography and Topological String Theory
Davide Gaiotto, Keyou Zeng
We study the dynamics of 2d fermions coupled to 3d Chern-Simons gauge fields. For gauge group and fermions in the fundamental representation, the resulting interfaces are c…
The Categorical 't Hooft Expansion
Davide Gaiotto
We review categorical aspects of 't Hooft's large expansion, which is expected to map any Quantum Field Theory of large matrices to a string theory. Our goal is to describe a g…
D-branes and the planar limit of Chern-Simons theory I: Link invariants
Davide Gaiotto, Suriyah Rajalingam Kannagi, Sergio Sanjurjo
We revisit the Holographic duality between Chern-Simons theory and the A-model Topological String Theory. We develop a strategy to systematically compute the large sa…
Renormalization Group flow in Schur quantization
Federico Ambrosino, Davide Gaiotto
We develop a general formalism to describe the Renormalization Group Flow of Schur indices and fusion algebras of BPS line defects in four-dimensional Supersymmetric Q…
Categorical 't Hooft expansion and chiral algebras
Davide Gaiotto, Adrián López-Raven, Hanne Silverans +1
Twisted holography captures protected aspects of well-known holographic dualities. We show how the holographic dual B-model background can be systematically derived from the 't Hoo…
Schur Quantization and Complex Chern-Simons theory
Davide Gaiotto, Jörg Teschner
Any four-dimensional Supersymmetric Quantum Field Theory with eight supercharges can be associated to a certain complex symplectic manifold called the "K-theoretic Coulomb branch"…
Categories of Line Defects and Cohomological Hall Algebras
Davide Gaiotto, Nikita Grygoryev, Wei Li
Any four-dimensional Supersymmetric Quantum Field Theory with eight supercharges can be associated to a monoidal category of BPS line defects. Any Coulomb vacuum of such a theory c…
Higher Operations in Perturbation Theory
Davide Gaiotto, Justin Kulp, Jingxiang Wu
We discuss the role of formal deformation theory in quantum field theories and present various ``higher operations'' which control their deformations, (generalized) OPEs, and anoma…
Quantum Analytic Langlands Correspondence
Davide Gaiotto, Jörg Teschner
The analytic Langlands correspondence describes the solution to the spectral problem for the quantised Hitchin Hamiltonians. It is related to the S-duality of super Yan…
Categorical Pentagon Relations and Koszul Duality
Davide Gaiotto, Ahsan Khan
The Kontsevich-Soibelman wall-crossing formula is known to control the jumping behavior of BPS state counting indices in four-dimensional theories with supersymmetr…
