Supersymmetric scale-separated AdS3 orientifold vacua of type IIB

Journal of High Energy Physics
I construct supersymmetric AdS3 vacua of type IIB string theory that exhibit parametric scale separation in the controlled regime. These solutions arise from compactifications on seven-dimensional manifolds equipped with co-closed G 2-structures, in the ...

On Low-Dimensional Solvmanifolds [PDF]

, 2009
A nilmanifold resp. solvmanifold is a compact homogeneous space of a connected and simply-connected nilpotent resp. solvable Lie group by a lattice, i.e. a discrete co-compact subgroup.

HOMOTOPY MINIMAL PERIODS FOR HYPERBOLIC MAPS ON INFRA-NILMANIFOLDS

, 2017
© 2017 Foundation Nagoya Mathematical Journal. In this paper, we show that for every nonnilpotent hyperbolic map f on an infra-nilmanifold, the set HPer(f) is cofinite in ℕ. This is a generalization of a similar result for expanding maps in Lee and Zhao (

Primary projections on L2 of a nilmanifold [PDF]

, 1979
Let N denote a connected, simply connected nilpotent Lie group with discrete cocompact subgroup Γ. Let U denote the quasi-regular representation on N on L2(NΓ). L2(NΓ) can be written as a direct sum of primary subspaces with respect to U.

Preserving asphericity of virtually nilpotent spaces under P-localization [PDF]

, 2003
For a set of prime numbers P, we study when the P-localization of an Eilenberg–Mac Lane space with virtually nilpotent fundamental group is again aspherical.

Ergodic Rotations of Nilmanifolds Conjugate to Their Inverses

, 2001
In answer to a question posed in [3], we give sufficient conditions on a Lie nilmanifold so that any ergodic rotation of the nilmanifold is metrically conjugate to its inverse.
