Best Approximation-Preserving Operators over Hardy Space

Fahreddin. G. Abdullayev, Viktor V. Savchuk, Maryna V. Savchuk

Let $T_{n}$ be the linear Hadamard convolution operator acting over Hardy space $H^{q}$ , $1 \leq q \leq \infty$ . We call $T_{n}$ a best approximation-preserving operator (BAP operator) if $T_…
