D=7 SU(2) Gauged Supergravity From D=10 Supergravity [PDF]
Phys.Lett. B476 (2000) 415-419, 1999 The theory of SU(2) gauged seven-dimensional supergravity is obtained by compactifying ten dimensional N=1 supergravity on the group manifold SU(2).

On Calabi‐Yau Manifolds at Strong Topological String Coupling
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...

New Black Hole Solutions in
Universe, 2021 We review a special class of N=2 supergravity model that interpolates all the single-dilaton truncations of the maximal SO(8) gauged supergravity.

An Sl(3,R) multiplet of 8-dimensional type II supergravity theories and the gauged supergravity inside [PDF]
Nucl.Phys. B602 (2001) 329-345, 2000 The so-called ``massive 11-dimensional supergravity'' theory gives, for one Killing vector, Romans' massive 10-dimensional supergravity in 10 dimensions, for two Killing vectors an Sl(2,Z) multiplet of massive 9-dimensional supergravity theories that can be obtained by standard generalized dimensional reduction type IIB supergravity and has been shown ...

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Spacetime Topology and the Laws of Black Hole-Soliton Mechanics
Entropy, 2017 The domain of outer communication of an asymptotically flat spactime must be simply connected. In five dimensions, this still allows for the possibility of an arbitrary number of 2-cycles supported by magnetic flux carried by Maxwell fields. As a result,

Recent and new results on octonionic Bergman and Szegö kernels
Mathematical Methods in the Applied Sciences, Volume 47, Issue 10, Page 7888-7901, 15 July 2024.Very recently one has started to study Bergman and Szegö kernels in the setting of octonionic monogenic functions. In particular, explicit formulas for the Bergman kernel for the octonionic unit ball and for the octonionic right half‐space as well as a formula for the Szegö kernel for the octonionic unit ball have been established.

Quantum No-Scale Regimes and String Moduli
Universe, 2018 We review that in no-scale models in perturbative string theory, flat, homogeneous and isotropic cosmological evolutions found at the quantum level can enter into “quantum no-scale regimes„ (QNSRs).
