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…

A Study on the Pointwise Time-Space Estimates of Fundamental Solution for Higher Order Schr\odinger Equation Whose Symbol Function is One Kind of Degenerate Polynomial
Myong-Jin Kim, Jin-Myong Kim
In this paper we investigated the point-wise time-space estimates of the fundamental solution for higher order Schrödinger equation. These estimates improve the result of Yao [2] a…
