Topological Phase Transitions [PDF]
This chapter aims to develop a systematic theory of topological phase transitions (TPTs) and explores a few typical examples, including (1) quantum phase transitions (QPTs), (2) galactic spiral structures, (3) electromagnetic eruptions on solar surface, (4) boundary-layer separation of fluid flows, and (5) interior separation of fluid flows.

On some kinds of dense orbits in general nonautonomous dynamical systems
We study the theory of universality for the nonautonomous dynamical systems from topological point of view related to hypercyclicity. The conditions are provided in a way that Birkhoff transitivity theorem can be extended.

On multi-transitivity with respect to a vector [PDF]
A topological dynamical system $(X,f)$ is said to be multi-transitive if for every $n\in\mathbb{N}$ the system $(X^{n}, f\times f^{2}\times \dotsb\times f^{n})$ is transitive.

Lifting Dynamical Properties to Hyperspaces
For a dynamical system (X,f), the passage of various dynamical properties such as transitivity, total transitivity, weakly mixing, mixing, topological exactness, topological conjugacy, to the hyperspace C(X) of X consisting of nonempty closed connected ...

PERCOLATION TRANSITION AND TOPOLOGY
A number of bidimensional random structures with increasing densities are simulated to explore possible links between Euler-Poincaré characteristic (EPC), or connectivity, and percolation threshold. For each structure model, the percolation threshold is compared with a number of typical points (extrema, zero crossings...) of the EPC curve.

Dynamical property of hyperspace on uniform space
First, we introduce the concepts of equicontinuity, expansivity , ergodic shadowing property, and chain transitivity in uniform space. Second, we study the dynamical properties of equicontinuity, expansivity , ergodic shadowing property, and chain ...

Quantum causal histories [PDF]
Quantum causal histories are defined to be causal sets with Hilbert spaces attached to each event and local unitary evolution operators. The reflexivity, antisymmetry, and transitivity properties of a causal set are preserved in the quantum history as ...

Semigroup Actions on Intuitionistic Fuzzy Metric Spaces
This paper investigates the dynamical systems in the context of topological semigroup actions on intuitionistic fuzzy metric spaces. We give some concepts such as topological transitivity, point transitivity, and densely point transitivity for such ...

Interactions Between Aging and Alzheimer’s Disease on Structural Brain Networks
Normative aging and Alzheimer’s disease (AD) propagation alter anatomical connections among brain parcels. However, the interaction between the trajectories of age- and AD-linked alterations in the topology of the structural brain network is not well ...
