Generalized α-Attractor Models from Elementary Hyperbolic Surfaces
Advances in Mathematical Physics, 2018 We consider generalized α-attractor models whose scalar potentials are globally well-behaved and whose scalar manifolds are elementary hyperbolic surfaces.

Chaos around the superposition of a monopole and a thick disk [PDF]
, 2000 We extend recent investigations on the integrability of oblique orbits of test particles under the gravitational field corresponding to the superposition of an infinitesimally thin disk and a monopole to the more realistic case, for astrophysical ...

Two-field cosmological α-attractors with Noether symmetry
Journal of High Energy Physics, 2019 We study Noether symmetries in two-field cosmological α-attractors, investigating the case when the scalar manifold is an elementary hyperbolic surface. This encompasses and generalizes the case of the Poincaré disk.

Dynamics of a rolling disc with an inclined sliding support
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021 Background. Nonholonomic mechanical systems can be models of various technical and robotic devices. Taking into account modern trends, the relevance of the study of nonholonomic systems is obvious and indisputable.

Time-Symmetric Initial Data for Multi-Body Solutions in Three Dimensions [PDF]
, 1995 Time-symmetric initial data for two-body solutions in three dimensional anti-deSitter gravity are found. The spatial geometry has constant negative curvature and is constructed as a quotient of two-dimensional hyperbolic space.

Black Hole Deconstruction [PDF]
, 2007 A D4-D0 black hole can be deconstructed into a bound state of D0 branes with a D6-anti-D6 pair containing worldvolume fluxes. The exact spacetime solution is known and resembles a D0 accretion disk surrounding a D6-anti-D6 core.
