From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

Joint transitivity for linear iterates

Forum of Mathematics, Sigma
We establish sufficient and necessary conditions for the joint transitivity of linear iterates in a minimal topological dynamical system with commuting transformations.

Linear dynamics of semigroups generated by differential operators

Open Mathematics, 2017
During the last years, several notions have been introduced for describing the dynamical behavior of linear operators on infinite-dimensional spaces, such as hypercyclicity, chaos in the sense of Devaney, chaos in the sense of Li-Yorke, subchaos, mixing ...

Magnetism-induced topological transition in EuAs3 [PDF]

Nature Communications, 2020
Abstract The nature of the interaction between magnetism and topology in magnetic topological semimetals remains mysterious, but may be expected to lead to a variety of novel physics. We systematically studied the magnetic semimetal EuAs 3 , demonstrating a magnetism-induced

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Genericity in Topological Dynamics

, 2006
We study genericity of dynamical properties in the space of homeomorphisms of the Cantor set and in the space of subshifts of a suitably large shift space.

Towards a theory of presence

Noûs, EarlyView.
Abstract The present paper presents a new (formal) theory of presence according to which, roughly, to be present at a place is to have a delegate located at that place. One crucial feature of the theory is that something can be present at a place without thereby being located there.

Anselm's Temporal‐Ontological Proof

Noûs, EarlyView.
ABSTRACT In his Reply to Gaunilo, Anselm presented two additional arguments for the existence of God beyond those that appear in the Proslogion. In “The Logical Structure of Anselm's Argument,” Robert M. Adams isolates each. One, he develops into a modal ontological argument along the lines of other 20th century ontological arguments (e.g., those of ...

Uncovering the Dependence of Cascading Failures on Network Topology by Constructing Null Models

Entropy, 2019
Cascading failures are the significant cause of network breakdowns in a variety of complex infrastructure systems. Given such a system, uncovering the dependence of cascading failures on its underlying topology is essential but still not well explored in
