On Marcinkiewicz-Zygmund inequalities and $A_{p}$ -weights for $L$ -shape arcs

Charles K. Chui, Lefan Zhong

Let $Γ$ be an $L$ -shape arc consisting of 2 line segments that meet at an angle different from $π$ in the complex $z$ -plane $\CC$. This paper is to investigate the behavior of the…

Order of uniform approximation by polynomial interpolation in the complex plane and beyond

Charles K. Chui, Lefan Zhong

For Lagrange polynomial interpolation on open arcs $X = γ$ in $C$ , it is well-known that the Lebesgue constant for the family of Chebyshev points ${\bf{x}}_n:=\{x_{n,j}\}^{n…

Analysis of a Direct Separation Method Based on Adaptive Chirplet Transform for Signals with Crossover Instantaneous Frequencies

Charles K. Chui, Qingtang Jiang, Lin Li +1

In many applications, it is necessary to retrieve the sub-signal building blocks of a multi-component signal, which is usually non-stationary in real-world and real-life applicatio…
