Linear dynamics of random products of weighted shifts

The aim of this article is to study the dynamics of random products of weighted shifts on a separable Fréchet sequence space. That is, given a measure-preserving dynamical system $(Ω, \mathcal{F}, μ, τ)$, a Fréchet sequence space $X$ with a basis $(e_n)_{n \geq 0}$, and a strongl...

Occurrence and controls of ~ 1 Hz waves in Mercury’s magnetosphere: insights from MESSENGER observations

<title>Abstract</title> Mercury’s magnetosphere is highly dynamic, with processes occurring on much shorter spatial and temporal scales than at Earth due to its weak magnetic field and proximity to the Sun. Wave-driven transport of energy and momentum is a key manifestation of th...
