Phase Retrieval in Hardy Space
Wei Qu, Xiao-Yun Sun, Guan-Tie Deng
This paper concerns the study of reconstructing a function in the Hardy space of the unit disc $\D$ from intensity measurements $|f(z)|,\ z\in \D.$ It's known as the problem of…

Sparse Approximation to the Dirac-δ Distribution
Wei Qu, Tao Qian, Guan-Tie Deng
The Dirac-δ distribution may be realized through sequences of convlutions, the latter being also regarded as approximation to the identity. The present study proposes the so called…

A sufficient condition for n-Best Kernel Approximation in Reproducing Kernel Hilbert Spaces
Wei Qu, Tao Qian, Guan-Tie Deng
We show that if a reproducing kernel Hilbert space consisting of functions defined on enjoys Double Boundary Vanishing Condition (DBVC) and Linear Independent Con…
