Intersecting attractors [PDF]

open access: yesPhysical Review D, 2009
We apply the entropy formalism to the study of the near-horizon geometry of extremal black p-brane intersections in D>5 dimensional supergravities. The scalar flow towards the horizon is described in terms an effective potential given by the superposition of the kinetic energies of all the forms under which the brane is charged.

Attractor as a convex combination of a set of attractors

open access: yesCommunications in Nonlinear Science and Numerical Simulation, 2021
Abstract This paper presents an effective approach to constructing numerical attractors of a general class of continuous homogenous dynamical systems: decomposing an attractor as a convex combination of a set of other existing attractors. For this purpose, the convergent Parameter Switching (PS) numerical method is used to integrate the underlying ...

On the homology of attractors

open access: bronzeTopology, 1976
neighborhood U satisfying X = f~ f”U. We will study the real homology of hyperbolic n=0 expanding attractors (defined below in the appendix) using the branched manifolds of [S] and dynamical properties of [l] and [71. One can assume that X is connected and in an appropriate sense oriented (expanding attractors are locally homeomorphic to Euclidean ...

ATTRACTORS IN SONG [PDF]

open access: yesNew Mathematics and Natural Computation, 2009
This paper summarizes our recent attempts to integrate action and perception within a single optimization framework. We start with a statistical formulation of Helmholtz's ideas about neural energy to furnish a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts.

Attractors in black [PDF]

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 ...

Mimetic Attractors [PDF]

open access: yesInternational Journal of Theoretical Physics, 2015
In this paper, we investigate the mathematical modeling for the cosmological attractors propagated in mimetic gravity upon which an interacting dark energy-dark matter is supposed to be existed. The average value of the interaction of these percentages, namely $ _i$ say, may be used to investigate generally the modeling of an attractor; the actual ...
