BPS Invariants for Generalized Toric Calabi-Yau Threefolds

Antoine Bourget, Peng Cheng, Quentin Lamouret

We apply topological vertex techniques to Calabi-Yau threefolds dual to brane webs where several 5-branes can end on the same 7-brane. In this context, we determine how topological…

Classifying Isolated Symplectic Singularities via 3d $N = 4$ Coulomb Branches

Antoine Bourget, Quentin Lamouret, Sinan Moura SoysÃ¼ren +1

Based on the Decay and Fission Conjecture, we provide a classification of unitary quivers whose 3d $N = 4$ Coulomb branches exhibit isolated singularities. This yields the…

From Quivers to Geometry: 5d Conformal Matter

Antoine Bourget, Mario De Marco, Michele Del Zotto +2

We show that all 5d balanced (ADE-shaped) special unitary quivers with no Chern-Simons level admit a UV completion which is a 5d conformal matter SCFT. We give explicit local Calab…

Zooming out of AdS $_{4} \times$ S $^{2} \times$ S $^{2}$ : The Branes behind the CFT's

Iosif Bena, Antoine Bourget, RaphaÃ«l Dulac +2

We reveal the supersymmetric brane configurations that give rise to AdS $_{4} \times$ S $^{2} \times$ S $^{2}$ supergravity solutions, which are holographic duals to three-dimensional $N = 4$ CFT…
