Communications in Mathematical Physics, 1985 There is no agreement in the literature regarding the definition of the concept of attractor in dynamical systems theory. The purpose of this paper is to propose another definition of this term, based on the concept of probable asymptotic behavior of orbits. Definitions of attractor range from the concepts of Lyapunov stability and asymptotic stability

Fortschritte 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 ...

"Large" strange attractors in the unfolding of a heteroclinic attractor
Discrete & Continuous Dynamical Systems, 2022 <p style='text-indent:20px;'>We present a mechanism for the emergence of strange attractors in a one-parameter family of differential equations defined on a 3-dimensional sphere. When the parameter is zero, its flow exhibits an attracting heteroclinic network (Bykov network) made by two 1-dimensional connections and one 2-dimensional separatrix ...

Structural Changes in NICs: Some Evidences on Attractor Points [PDF]
In this paper we develop a regression and a kernel density based model for finding fixed points and attractors of dynamical systems to explore attractors of structural change for NICs.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

Unifying attractor and non-attractor models of inflation under a single soft theorem [PDF]
, 2023 We study the generation of local non-Gaussianity in models of canonical single field inflation when their backgrounds are either attractor or non-attractor.

Control in Boolean Networks With Model Checking
Frontiers in Applied Mathematics and Statistics, 2022 Understanding control mechanisms in biological systems plays a crucial role in important applications, for instance in cell reprogramming. Boolean modeling allows the identification of possible efficient strategies, helping to reduce the usually high and
