Minkowski $_{4}$ $\times$ $S^{2}$ solutions of IIB supergravity

Fabio Apruzzi, Jakob C. Geipel, Andrea Legramandi +2

We classify $N = 2$ Minkowski $_{4}$ solutions of IIB supergravity with an $S U (2)_{R}$ symmetry geometrically realized by an $S^{2}$ -foliation in the remaining six dimensions. Fo…

Instantons on Calabi-Yau and hyper-Kähler cones

Jakob C. Geipel, Marcus Sperling

The instanton equations on vector bundles over Calabi-Yau and hyper-Kähler cones can be reduced to matrix equations resembling Nahm's equations. We complement the discussion of Her…

Sasakian quiver gauge theories and instantons on cones over round and squashed seven-spheres

Jakob C. Geipel, Olaf Lechtenfeld, Alexander D. Popov +1

We study quiver gauge theories on the round and squashed seven-spheres, and orbifolds thereof. They arise by imposing $G$ -equivariance on the homogeneous space $G/H=\mathrm{SU}(4)/…

Generalised Calibrations in AdS backgrounds from Exceptional Sasaki-Einstein Structures

Oscar de Felice, Jakob Geipel

We study generalised calibrations described by Exceptional Sasaki-Einstein structures on AdS backgrounds in type IIB and M-theory, placing the focus on the generalised Reeb vectors…

Sasakian quiver gauge theory on the Aloff-Wallach space $X_{1, 1}$

Jakob C. Geipel

We consider the SU(3)-equivariant dimensional reduction of gauge theories on spaces of the form $M^{d} \times X_{1, 1}$ with d-dimensional Riemannian manifold $M^{d}$ and the Aloff-Wall…
