A large class of supergravities in diverse dimensions are surveyed. This includes maximal
supergravities, their general gaugings in the framework of embedding tensor formalism …

A bstract We construct the four-derivative supersymmetric extension of (1, 0), 6D
supergravity coupled to Yang-Mills and hypermultiplets. The hypermultiplet scalars are …

Gauging isometries of four-dimensional N= 2 supergravity theories yields an N= 2
supersymmetric theory with a scalar potential. In this paper, we study the well-known …

We construct examples of complete quaternionic K\" ahler manifolds with an end of finite
volume, which are not locally homogeneous. The manifolds are aspherical with fundamental …

We prove that the one-loop deformation of any quaternionic Kähler manifold in the class of c-
map spaces is locally inhomogeneous. As a corollary, we obtain that the full isometry group …

For each non‐flat, unimodular Ricci soliton solvmanifold (S 0, g 0) (S_0,g_0), we construct a
one‐parameter family of complete, expanding, gradient Ricci solitons that admit a …

The current Standard Model (SM) of physics [15–18] is one of the greatest achievements of
humanity. It has involved the most brilliant thinkers and scientists of History, from Ancient …

We study the behavior of connections and curvature under the HK/QK correspondence,
proving simple formulae expressing the Levi-Civita connection and Riemann curvature …

We classify Einstein metrics on R 4 invariant under a four-dimensional group of isometries
including a principal action of the Heisenberg group. We consider metrics which are either …

Q-map spaces form an important class of quaternionic K\" ahler manifolds of negative scalar
curvature. Their one-loop deformations are always inhomogeneous and have been used to …
