Disjoint strong transitive operators on Hilbert C*-modules
Song-Ung Ri, Hyon-Hui Ju
This paper is about disjoint F-transitive operators on Hilbert C*-modules, where F is a finitely invariant Furstenberg family of subsets of N. We characterize disjoint F-transitivi…

Frequent, disjoint hypercyclicity and strong topological transitivity of generalized weighted shift operators on Hilbert C-modules
Song-Ung Ri, Hyon-Hui Ju, Jin-Myong Kim
In this paper we study some dynamical properties such as Frequent Hypercyclicity Criterion, chaos, disjoint hypercyclicity and F-transitivity via Furstenberg family F for generaliz…

A note on disjoint hypercyclicity for invertible bilateral pseudo-shifts on
SongUng Ri, HyonHui Ju, JinMyong Kim
We first give a note on disjoint hypercyclicity for invertible bilateral pseudo-shifts on , . It is already known that if a tuple of bilatera…
