Various notions of topological transitivity in non-autonomous discrete dynamical systems
Applied General TopologyWe consider various strengthenings of the notion of topological transitivity in non-autonomous discrete dynamical systems. We give many equivalent conditions foreach of these notions and present the implications among them. We also considerrearrangements

IEEE Transactions on Power Systems, 2023 The topology transition problem of transmission networks is becoming increasingly crucial with topological flexibility more widely leveraged to promote high renewable penetration. This paper proposes a novel methodology to address this problem. Aiming at achieving a bumpless topology transition regarding both static and dynamic performance, this ...

IEEE Transactions on Power Systems, 2022 Network topology has significant impacts on operational performance of power systems. While extensive research efforts have been devoted to optimization of network topology for improving various system performances, the problem of how to transition from the initial topology to the desired optimal topology requires study.

Topological Transitions in Metamaterials [PDF]
Science, 2012 Manipulating Optical TopologyPhase transitions in solid-state systems are often associated with a drastic change in the properties of that system. For example, metal-to-insulator transition or magnetic-to-nonmagnetic states find wide application in memory storage technology.

Chromatin Topological Transitions [PDF]
Progress of Theoretical Physics Supplement, 2011 (Received February 24, 2011)DNA transaction events occurring during a cell cycle (transcription, repair, replication)are always associated with severe topological constraints on the double helix. However, sincenuclear DNA is bound to various proteins (including histones) that control its accessibilityand 3D organization, these topological constraints ...

Topological transition on the conformal manifold [PDF]
Physical Review Research, 2020 Despite great successes in the study of gapped phases, a comprehensive understanding of the gapless phases and their transitions is still under developments. In this paper, we study a general phenomenon in the space of (1+1)$d$ critical phases with fermionic degrees of freedom described by a continuous family of conformal field theories (CFT), a.k.a ...

Topological transitivity of translation operators in a non-separable Hilbert space
Karpatsʹkì Matematičnì Publìkacìï, 2023 We consider a Hilbert space of entire analytic functions on a non-separable Hilbert space, associated with a non-separable Fock space. We show that under some conditions operators, like the differentiation operators and translation operators, are ...
