A note on the zeros of Jensen polynomials
Young-One Kim, Jungseob Lee
A recent result of Griffin, Ono, Rolen and Zagier on Jensen polynomials related with the Riemann zeta function is improved.
The convergence of a sequence of polynomials and the distribution of their zeros
Min-Hee Kim, Young-One Kim, Jungseob Lee
Suppose that is a sequence of polynomials, converges for every non-negative integer , and that the limit is not for some…
On the Pólya-Wiman properties of Differential Operators
Min-Hee Kim, Young-One Kim
Let be a formal power series with real coefficients, and let denote differentiation. It is shown that "for every real polynomial there is a positive int…
On the flips for a synchronized system
Hyekyoung Choi, Young-One Kim
It is shown that if an infinite synchronized system has a flip, then it has infinitely many non-conjugate flips, and that the result cannot be extended to the class of coded system…

Young-One Kim, Sieye Ryu
In the case when is a sofic shift and is a homeomorphism such that and , the number of points in that are fixed by $σ_X^…
