Projecting Gravitational Fluctuations onto Near-Horizon Throats

Alejandro Cabo-Bizet, Vasil Dimitrov, Dario Martelli +1

We show that, for stationary geometries whose linearized fluctuation equations separate into radial and angular Heun equations, a pair of diffeomorphisms projects the full problem…

Half-Spacetime Gauging of 2-Group Symmetry in 3d

Davide Bason, Wei Cui, Lorenzo Ruggeri

We construct a class of non-invertible duality defects, in (2+1)d quantum field theories, arising from half-spacetime gauging of a 2-group symmetry. Starting from a parent theory w…

Contour Integral for the Partition Function of Topologically Twisted on and Physical Fluxes

Lorenzo Ruggeri

We compute the contour integral for the partition function of an topologically twisted theory on , dimensionally reducing from an $\mathcal{N…

Exact Results for SYM on and with Conical Singularities

Lorenzo Ruggeri

Starting from a theory on and dimensionally reducing, we compute the full partition function, including flux and instanton contributions, for an the…

Codimension-Two Defects and SYM on Orbifolds

Roman Mauch, Lorenzo Ruggeri

We study SYM theories on spaces with orbifold singularities via an equivalent description in terms of gauge theories on smooth manifolds with insertions of Gukov-Witten and…

Non-Invertible Surface Defects in 2+1d QFTs from Half Spacetime Gauging

Wei Cui, Babak Haghighat, Lorenzo Ruggeri

We study duality defects in 2+1d theories with $\bZ^{(0)}_N\times\bZ^{(1)}_N$ global symmetry and trivial mixed 't Hooft anomaly. By gauging these symmetries simultaneously in half…

Super Yang-Mills on Branched Covers and Weighted Projective Spaces

Roman Mauch, Lorenzo Ruggeri

In this work we conjecture the Coulomb branch partition function, including flux and instanton contributions, for the vector multiplet on weighted projective space…

From 5d Flat Connections to 4d Fluxes (the Art of Slicing the Cone)

Jim Lundin, Roman Mauch, Lorenzo Ruggeri

We compute the Coulomb branch partition function of the 4d vector multiplet on closed simply-connected quasi-toric manifolds . This includes a large class of the…

Index of the Transversally Elliptic Complex in Pestunization

Roman Mauch, Lorenzo Ruggeri

In this note we present a formula for the equivariant index of the cohomological complex obtained from localization of SYM on simply-connected compact four-manifold…

SYM on Quotients of Spheres and Complex Projective Spaces

Jim Lundin, Lorenzo Ruggeri

We introduce a generic procedure to reduce a supersymmetric Yang-Mills (SYM) theory along the Hopf fiber of squashed with isometry, down to the $\mathbb{CP}^{r-…

Cohomological Localization of Gauge Theories with Matter

Guido Festuccia, Anastasios Gorantis, Antonio Pittelli +2

We construct a large class of gauge theories with extended supersymmetry on four-dimensional manifolds with a Killing vector field and isolated fixed points. We extend previous res…
