Relationships among Various Chaos for Linear Semiflows Indexed with Complex Sectors

open access: yesMathematics
In this paper, we investigate the relationships among point transitivity, topological transitivity, Li–Yorke chaos, and the existence of irregular vectors for a linear semiflow {Tt}t∈Δ indexed with a complex sector.

Parry’s topological transitivity and $f$-expansions [PDF]

open access: yesProceedings of the American Mathematical Society, 2015
In his 1964 paper on f-expansions, Parry studied piecewise-continuous, piecewise-monotonic maps F of the interval [0,1), and introduced a notion of topological transitivity different from any of the modern definitions. This notion, which we call Parry topological transitivity, (PTT) is that the backward orbit O^-(x)={y:x=F^ny for some n\ge 0} of some x\

Limit Orders and Knightian Uncertainty

open access: yesInternational Economic Review, Volume 67, Issue 1, Page 353-363, February 2026.
ABSTRACT A wide variety of financial instruments allows risk‐averse traders to reduce their exposure to risk. This raises the question of what financial instruments allow ambiguity‐averse traders to reduce their exposure to ambiguity. We show in this paper that price‐contingent orders, such as limit orders, are sufficient: In a two‐period trading model,

Dynamic Reconfiguration of Functional Topology in Human Brain Networks: From Resting to Task States

open access: yesNeural Plasticity, 2020
Task demands evoke an intrinsic functional network and flexibly engage multiple distributed networks. However, it is unclear how functional topologies dynamically reconfigure during task performance. Here, we selected the resting- and task-state (emotion

Nonemptiness of the Alpha‐Core

open access: yesJournal of Public Economic Theory, Volume 28, Issue 1, February 2026.
ABSTRACT We prove nonemptiness of the α $\alpha $‐core for balanced games with nonordered preferences, extending and generalizing in several aspects the results of Scarf (1971), Border (1984), Florenzano (1989), Yannelis (1991b), and Kajii (1992). In particular, we answer an open question in Kajii (1992) regarding the applicability of the nonemptiness ...

An Improved Chaotic Motion Path Planner for Autonomous Mobile Robots Based on a Logistic Map

open access: yesInternational Journal of Advanced Robotic Systems, 2013
This paper presents a chaotic motion path planner based on a Logistic Map (SCLCP) for an autonomous mobile robot to cover an unknown terrain randomly, namely entirely, unpredictably and evenly.

The cosymplectic Chern–Hamilton conjecture

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract In this paper, we study the Chern–Hamilton energy functional on compact cosymplectic manifolds, fully classifying in dimension 3 those manifolds admitting a critical compatible metric for this functional. This is the case if and only if either the manifold is co‐Kähler or if it is a mapping torus of the 2‐torus by a hyperbolic toral ...

On the apparent failure of the topological theory of phase transitions

open access: yes, 2015
The topological theory of phase transitions has its strong point in two theorems proving that, for a wide class of physical systems, phase transitions necessarily stem from topological changes of some submanifolds of configuration space.
