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…
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…
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…
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…
