Classification of left-invariant Einstein metrics on $SL (2, R) \times SL (2, R)$ that are bi-invariant under a one-parameter subgroup

Vicente Cortés, Jeremias Ehlert, Alexander S. Haupt +1

We classify all left-invariant pseudo-Riemannian Einstein metrics on $SL (2, R) \times SL (2, R)$ that are bi-invariant under a one-parameter subgrou…

A non-existence theorem for N>16 supersymmetric AdS3 backgrounds

A. S. Haupt, S. Lautz, G. Papadopoulos

We show that there are no smooth warped AdS $_{3}$ solutions in 10- and 11-dimensional supergravities which preserve strictly more than 16 supersymmetries and have internal space a co…

Chern-Simons flows on Aloff-Wallach spaces and Spin(7)-instantons

Alexander S. Haupt, Tatiana A. Ivanova, Olaf Lechtenfeld +1

Due to their explicit construction, Aloff-Wallach spaces are prominent in flux compactifications. They carry G_2-structures and admit the G_2-instanton equations, which are natural…
