A note on shadowing properties
Hahng-Yun Chu, Dae Hwan Goo, Se-Hyun Ku
Let be the space of -vector fields on endowed with the -topology and let be an isolated set for a . In this pap…
Polycycle omega-limit sets of flows on the compact Riemann surfaces and Eulerian path
Jaeyoo Choy, Hahng-Yun Chu
Let be a pair of a closed oriented surface and be a real analytic flow with finitely many singularities. Let be a point of with the polycycle -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…
A Mazur-Ulam theorem for Mappings of conservative distance in non-Archimedean -normed spaces
Hahng-Yun Chu, Se-Hyun Ku
In this article, we study the notions of -isometries in non-Archimedean -normed spaces over linear ordered non-Archimedean fields, and prove the Mazur-Ulam theorem in the spa…
On Homoclinic points, Recurrences and Chain recurrences of volume-preserving diffeomorphisms without genericity
Jaeyoo Choy, Hahng-Yun Chu, Min Kyu Kim
Let be a manifold with a volume form and be a diffeomorphism of class that preserves . In this paper, we do \textit{not} assume is $\ma…
Dynamics of riemannian 1-foliations on -manifolds
Jaeyoo Choy, Hahng-Yun Chu
In this paper we study several dynamical properties of the riemannian -dimensional foliation on an oriented closed 3-manifold . Carriere classified such pairs $…
On the Cauchy--Rassias Inequality and Linear n-Inner Product Preserving Mappings
Choonkil Baak, Hahng-Yun Chu, Mohammad Sal Moslehian
We prove the Cauchy-Rassias stability of linear n-inner product preserving mappings in -inner product Banach spaces. We apply the Cauchy-Rassias inequality that plays an influen…
