A note on shadowing properties

Hahng-Yun Chu, Dae Hwan Goo, Se-Hyun Ku

Let $X^{1} (M)$ be the space of $C^{1}$ -vector fields on $M$ endowed with the $C^{1}$ -topology and let $Λ$ be an isolated set for a $X \in X^{1} (M)$ . In this pap…

Polycycle omega-limit sets of flows on the compact Riemann surfaces and Eulerian path

Jaeyoo Choy, Hahng-Yun Chu

Let $(S, Φ)$ be a pair of a closed oriented surface and $Φ$ be a real analytic flow with finitely many singularities. Let $x$ be a point of $S$ with the polycycle $ω$ -limit set $ω(x…

A topological characterization of omega-limit sets on dynamical systems

Hahng-Yun Chu, Ahyoung Kim, Jong-Suh Park

In this article, we deal with several notions in dynamical systems. Firstly, we prove that both closure function and orbital function are idempotent on set-valued dynamical systems…

On Homoclinic points, Recurrences and Chain recurrences of volume-preserving diffeomorphisms without genericity

Jaeyoo Choy, Hahng-Yun Chu, Min Kyu Kim

Let $M$ be a manifold with a volume form $ω$ and $f : M \to M$ be a diffeomorphism of class $C^{1}$ that preserves $ω$ . In this paper, we do \textit{not} assume $f$ is $\ma…
