Attractors in black

open access: yesFortschritte der Physik, 2008
AbstractWe review recent results in the study of attractor horizon geometries (with non‐vanishing Bekenstein‐Hawking entropy) of dyonic extremal d = 4 black holes in supergravity. We focus on 𝒩 = 2, d = 4 ungauged supergravity coupled to a number nVof Abelian vector multiplets, outlining the fundamentals of the special Kähler geometry of the vector ...

On coincidence and common fixed points of nearly densifying mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Coincidence and common fixed point theorems for certain new classes of nearly densifying mappings are established. Our results extend, improve, and unify a lot of previously known theorems.

A Novel Multi-Attractor Period Multi-Scroll Chaotic Integrated Circuit Based on CMOS Wide Adjustable CCCII

open access: yesIEEE Access, 2019
This paper proposes a multi-attractor period multi-scroll chaotic system and a second-generation current-controlled current conveyor (CCCII) with a wide tunable range of intrinsic resistance. The newly proposed multi-attractor period multi-scroll chaotic

Measure attractors and Markov attractors [PDF]

open access: yesDynamical Systems, 2008
The actions induced by a random dynamical system on spaces of probability measures on the state space are investigated, and generalisations of the notion of an attractor are discussed and compared. For the particular case of a random dynamical system generated by a stochastic differential equation the notion of an attractor for the associated Markov ...

Quantum Attractor Flows [PDF]

open access: yes, 2007
Motivated by the interpretation of the Ooguri-Strominger-Vafa conjecture as a holographic correspondence in the mini-superspace approximation, we study the radial quantization of stationary, spherically symmetric black holes in four dimensions.

Fixed Point Attractor Theory Bridges Structure and Function in C. elegans Neuronal Network

open access: yesFrontiers in Neuroscience, 2022
Understanding the structure–function relationship in a neuronal network is one of the major challenges in neuroscience research. Despite increasing researches at circuit connectivity and neural network structure, their structure-based biological ...

Inflation as an attractor in scalar cosmology

open access: yes, 2013
We study an inflation mechanism based on attractor properties in cosmological evolutions of a spatially flat Friedmann-Robertson-Walker spacetime based on the Einstein-scalar field theory. We find a new way to get the Hamilton-Jacobi equation solving the
