Rational Approximation, Hardy Space - Decomposition of Functions in $L_{p}, p < 1$ : Further Results in Relation to Fourier Spectrum Characterization of Hardy Spaces

Guantie Deng, Tao Qian

Subsequent to our recent work on Fourier spectrum characterization of Hardy spaces $H^{p} (R)$ for the index range $1 \leq p \leq \infty,$ in this paper we prove further result…

Minimax principle and lower bounds in H $^{2}$ -rational approximation

Laurent Baratchart, Sylvain Chevillard, Tao Qian

We derive some lower bounds in rational approximation of given degree to functions in the Hardy space $H^{2}$ of the disk. We apply these to asymptotic errors rates in approximation…
