A remark on the Sibony function
Marek Jarnicki, Peter Pflug
We present an effective formula for the Sibony function for all Reinhardt domains.
An Adiabatic Decomposition of the Hodge Cohomology of Manifolds Fibred over Graphs
Karsten Fritzsch
In this article we use the combinatorial and geometric structure of manifolds with embedded cylinders in order to develop an adiabatic decomposition of the Hodge cohomology of thes…
Probing the universality of synchronised hair around rotating black holes with Q-clouds
Carlos Herdeiro, Jutta Kunz, Eugen Radu +1
Recently, various families of black holes (BHs) with synchronised hair have been constructed. These are rotating BHs surrounded, as fully non-linear solutions of the appropriate Ei…
Wormholes Immersed in Rotating Matter
Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2
We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asympt…
Static Orbits in Rotating Spacetimes
Lucas G. Collodel, Burkhard Kleihaus, Jutta Kunz
We show that under certain conditions an axisymmetric rotating spacetime contains a ring of points in the equatorial plane, where a particle at rest with respect to an asymptotic s…
Symbolic vs. Bounded Synthesis for Petri Games
Bernd Finkbeiner, Manuel Gieseking, Jesko Hecking-Harbusch +1
Petri games are a multiplayer game model for the automatic synthesis of distributed systems. We compare two fundamentally different approaches for solving Petri games. The symbolic…
Riddled Basins of Attraction in Systems Exhibiting Extreme Events
Arindam Saha, Ulrike Feudel
Using a system of two FitzHugh-Nagumo units, we demonstrate the occurrence of riddled basins of attraction in delay-coupled systems as the coupling between the units is increased.…
Squashed, magnetized black holes in minimal gauged supergravity
Jose Luis Blázquez-Salcedo, Jutta Kunz, Francisco Navarro-Lérida +1
We construct a new class of black hole solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant. These configurations are cohomogene…
New black holes in minimal gauged supergravity: Deformed boundaries and frozen horizons
Jose Luis Blázquez-Salcedo, Jutta Kunz, Francisco Navarro-Lérida +1
A new class of black hole solutions of the five dimensional minimal gauged supergravity is presented. They are characterized by the mass, the electric charge, two equal magnitude a…
Can clustering scale sublinearly with its clusters? A variational EM acceleration of GMMs and -means
Dennis Forster, Jörg Lücke
One iteration of standard -means (i.e., Lloyd's algorithm) or standard EM for Gaussian mixture models (GMMs) scales linearly with the number of clusters , data points , an…
Geodesic motion in the five-dimensional Myers-Perry-AdS spacetime
Saskia Grunau, Hendrik Neumann, Stephan Reimers
In this article we study the geodesic motion of test particles and light in the five-dimensional Myers-Perry-anti de Sitter spacetime. We derive the equations of motion and present…
Uniqueness theorem for static phantom wormholes in Einstein-Maxwell-dilaton theory
Boian Lazov, Petya Nedkova, Stoytcho Yazadjiev
We prove a uniqueness theorem for traversable wormhole solutions in the Einstein-Maxwell-dilaton gravity with a phantom scalar field and a possible phantom electromagnetic field. I…
Radially Excited AdS Black Holes in Einstein--Maxwell--Chern--Simons Theory
Jose Luis Blázquez-Salcedo
In the large coupling regime of the 5-dimensional Einstein--Maxwell--Chern--Simons theory, charged and rotating cohomogeneity-1 black holes form sequences of extremal and non-extre…
The observing campaign on the deep-space debris WT1190F as a test case for short-warning NEO impacts
Marco Micheli, Alberto Buzzoni, Detlef Koschny +13
On 2015 November 13, the small artificial object designated WT1190F entered the Earth atmosphere above the Indian Ocean offshore Sri Lanka after being discovered as a possible new…
Exact Ground States of the Kaya-Berker Model
Sebastian von Ohr, Alexander K. Hartmann
Here we study the two-dimensional Kaya-Berker model, with a site occupancy p of one sub lattice, by using a polynomial-time exact ground-state algorithm. Thus, we were able to obta…
Distribution of diameters for Erdös-Rényi random graphs
Alexander K. Hartmann, Marc Mézard
We study the distribution of diameters d of Erdös-Rényi random graphs with average connectivity c. The diameter d is the maximum among all shortest distances between pairs of nodes…
Roper resonances and quasi-normal modes of Skyrmions
C. Adam, M. Haberichter, T. Romanczukiewicz +1
Radial vibrations of charge one hedgehog Skyrmions in the full Skyrme model are analysed. We investigate how the properties of the lowest resonance modes (quasi normal modes) - the…
Strong Coupling of Collection of Emitters on Hyperbolic Meta-Material
Svend-Age Biehs, Chenran Xu, Girish S. Agarwal
Recently considerable effort is devoted to the realization of the strong coupling regime of the radiation matter interaction in the context of emitter at a meta surface. The strong…
Large-deviation properties of the extended Moran model
Alexander K. Hartmann, Thierry E. Huillet
The distributions of the times to the first common ancestor t_mrca is numerically studied for an ecological population model, the extended Moran model. This model has a fixed popul…
Wormhole solutions with a complex ghost scalar field and their instability
Vladimir Dzhunushaliev, Vladimir Folomeev, Burkhard Kleihaus +1
We study compact configurations with a nontrivial wormholelike spacetime topology supported by a complex ghost scalar field with a quartic self-interaction. For this case, we obtai…
Einstein-Maxwell-Chern-Simons Black Holes
Jutta Kunz, Jose Luis Blázquez-Salcedo, Francisco Navarro-Lérida +1
Black holes in 5-dimensional Einstein-Maxwell-Chern-Simons (EMCS) theory and their intriguing properties are discussed. For the special case of the CS coupling constant ,…
