Generalized Attractor Points in Gauged Supergravity [PDF]
, 2011 The attractor mechanism governs the near-horizon geometry of extremal black holes in ungauged 4D N=2 supergravity theories and in Calabi-Yau compactifications of string theory.

Taking into account the complexity in the tasks of transport demand
Интеллект. Инновации. Инвестиции, 2023 The article describes the theoretical basis for taking into account the complexity in solving problems of transport demand, the analysis of the concept of “self-organized criticality” is carried out.

Attractor behaviour in multifield inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We study multifield inflation in scenarios where the fields are coupled non-minimally to gravity via ξI(ϕI)n gμνRμν, where ξI are coupling constants, ϕI the fields driving inflation, gμν the space-time metric, Rμν the Ricci tensor, and n>0.

Global attractors for strongly damped wave equations with displacement dependent damping and nonlinear source term of critical exponent [PDF]
, 2011 In this paper the long time behaviour of the solutions of 3-D strongly damped wave equation is studied. It is shown that the semigroup generated by this equation possesses a global attractor in H_{0}^{1}(\Omega)\times L_{2}(\Omega) and then it is proved ...

The Neuroanatomical Ultrastructure and Function of a Biological Ring Attractor
Neuron, 2019 Neural representations of head direction have been discovered in many different species. A large body of theoretical work has proposed that the dynamics associated with these representations might be generated, maintained, and updated by recurrent ...

The non-equilibrium attractor for kinetic theory in relaxation time approximation [PDF]
Journal of High Energy Physics, 2018 I demonstrate that the concept of a non-equilibrium attractor can be extended beyond the lowest-order moments typically considered in hydrodynamic treatments.

Revisiting non-Gaussianity from non-attractor inflation models [PDF]
, 2017 Non-attractor inflation is known as the only single field inflationary scenario that can violate non-Gaussianity consistency relation with the Bunch-Davies vacuum state and generate large local non-Gaussianity.

Constrained attractor selection using deep reinforcement learning [PDF]
Journal of Vibration and Control, 2019 This study describes an approach for attractor selection (or multistability control) in nonlinear dynamical systems with constrained actuation. Attractor selection is obtained using two different deep reinforcement learning methods: (1) the cross-entropy

Chaotic inflation limits for non-minimal models with a Starobinsky attractor [PDF]
, 2014 We investigate inflationary attractor points by analyzing non-minimally coupled single field inflation models in two opposite limits; the `flat' limit in which the first derivative of the conformal factor is small and the `steep' limit, in which the ...
