Shadowing and structural stability for operators

Ergodic Theory and Dynamical Systems, 2020
A well-known result in the area of dynamical systems asserts that any invertible hyperbolic operator on any Banach space is structurally stable. This result was originally obtained by Hartman in 1960 for operators on finite-dimensional spaces.

Shadowing

Dying for the nation, 2020
Shadowing is a voluntary experience with an Attending Physician, Physician’s Assistant or Physical Therapist in the Department of Orthopaedics and Rehabilitation. Those approved are permitted to shadow over the course of a 21-day period within a calendar

Generalized Hyperbolicity and Shadowing in $L^p$ spaces

, 2020
It is rather well-known that hyperbolic operators have the shadowing property. In the setting of finite dimensional Banach spaces, having the shadowing property is equivalent to being hyperbolic. In 2018, Bernardes et al. constructed an operator with the

Some Varieties of Shadow Illusions: Split Shadows, Occluded Shadows, Stolen Shadows, and Shadows of Shadows

Perception, 2012
Shadows are visual objects and as such are subject to preference rules for segmenting the visual scene (such as Gestalt laws). These rules govern shadows along two dimensions: their general unity and individuation (eg they describe a certain area as a unitary shadow as opposed to a set of two distinct shadows), and their being the of a given object ...

HumanPlus: Humanoid Shadowing and Imitation from Humans

Conference on Robot Learning
One of the key arguments for building robots that have similar form factors to human beings is that we can leverage the massive human data for training. Yet, doing so has remained challenging in practice due to the complexities in humanoid perception and

Shadowing: What is It? How to Use It. Where Will It Go?

RELC Journal : A Journal of Language Teaching and Research in Southeast Asia, 2018
Twenty-five years have passed since a teaching technique, called shadowing, was introduced in Japanese EFL contexts. Recently, this technique has gradually been recognized around the world. Given that many studies have been published about shadowing, the

Shadows

Applied Optics, 2015
We investigate the brightness distribution in and around outdoor shadows (for a variety of sky conditions) using modeling and field measurements. The dominant factor influencing the brightness of a shadow is the solid angle subtended by the object blocking the Sun.

Homoclinic Shadowing

Journal of Dynamics and Differential Equations, 2005
The famous Smale-Birkhoff theorem provides a criterion for chaotic behavior of dynamical systems. More precisely, the existence of transversal homoclinic orbits leads to hyperbolic sets containing the shift, a horseshoe and thus chaotic dynamics. In this interesting and well-written paper, the authors present a new and rigorous method to establish the ...
