Open AccessTCFHs and hidden symmetries of type IIA AdS backgrounds
We present the twisted covariant form hierarchies (TCFHs) of warped (massive) IIA AdS backgrounds. As a consequence we demonstrate that all Killing spinor form bilinears satisfy a generalisation of the conform...

Open AccessThe TCFHs of D = 11 AdS backgrounds and hidden symmetries
We present the TCFHs of all AdS backgrounds of 11-dimensional supergravity and explore some of the properties of the associated connections. Therefore, we demonstrate that all Killing spinor bilinears satisfy ...

Open AccessTCFHs, IIB warped AdS backgrounds and hidden symmetries
We present the twisted covariant form hierarchies (TCFHs) on the internal spaces of all type IIB warped AdS backgrounds. As a result we demonstrate that the form bilinears on the internal spaces satisfy a gene...

Open AccessTCFHs, hidden symmetries and type II theories
We present the twisted covariant form hierarchies (TCFH) of type IIA and IIB 10-dimensional supergravities and show that all form bilinears of supersymmetric backgrounds satisfy the conformal Killing-Yano equa...

B3 agonists or anticholinergics in the treatment of the lower urinary tract dysfunction in patients with multiple sclerosis?—A randomized study
Multiple sclerosis (MS) is the most frequent autoimmune demyelinating disease of the central nervous system. MS patients usually present with lower urinary tract dysfunction (LUTD). Objective of this study is ...

Open AccessTwisted form hierarchies, Killing-Yano equations and supersymmetric backgrounds
We show that the Killing spinor equations of all supergravity theories which may include higher order corrections on a (r,s)-signature spacetime are associated with twisted covariant form hierarchies. These hi...

Open AccessA non-existence theorem for N > 16 supersymmetric AdS3 backgrounds
We show that there are no smooth warped AdS3 solutions in 10- and 11- dimensional supergravities which preserve strictly more than 16 supersymmetries and have internal space a compact without boundary manifold.
