CHAOS FOR BACKWARD SHIFT OPERATORS

International Journal of Bifurcation and Chaos, 2002
Backward shift operators provide a general class of linear dynamical systems on infinite dimensional spaces. Despite linearity, chaos is a phenomenon that occurs within this context. In this paper we give characterizations for chaos in the sense of Auslander and Yorke [1980] and in the sense of Devaney [1989] of weighted backward shift operators and ...

Jℱ-Class Weighted Backward Shifts

International Journal of Bifurcation and Chaos, 2018
In this article [Formula: see text]-class operators are introduced and some basic properties of [Formula: see text]-vectors are given. The [Formula: see text]-class operators include the [Formula: see text]-class operators and [Formula: see text]-class operators introduced by Costakis and Manoussos in 2008.

Forward versus Backward Shift Rotation

Proceedings of the Human Factors Society Annual Meeting, 1989
The U.S. Bureau of Mines has been involved in the study of guidelines for the design of shiftwork schedules. One popular suggestion offered by shiftwork researchers and consultants is to establish schedules that rotate in a forward direction (Day to Afternoon to Nights) rather than backward (Day to Night to Afternoon).
