Extracting Complements and Substitutes from Sales Data: A Network Perspective
Yu Tian, Sebastian Lautz, Alisdiar O. G. Wallis +1
The complementarity and substitutability between products are essential concepts in retail and marketing. Qualitatively, two products are said to be substitutable if a customer can…
Geometrical Aspects of AdS/CFT
Sebastian Lautz
In this thesis, we investigate all warped AdS and AdS backgrounds with the most general allowed fluxes that preserve more than 16 supersymmetries in 10- and 11-dimensional…
A uniqueness theorem for warped Minkowski backgrounds with fluxes
S. Lautz, G. Papadopoulos
We demonstrate that warped Minkowski space backgrounds, , , that preserve strictly more than 16 supersymmetries in and type II $d…
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 solutions in 10- and 11-dimensional supergravities which preserve strictly more than 16 supersymmetries and have internal space a co…
