Approximation of Bergman kernels by rational functions with fixed poles

Stanislav Chaichenko

We solved the problem of the best rational approximation of the Bergman kernels on the unit circle of the complex plane in the quadratic and uniform metrics.

Convergence of Fourier series on the system of rational functions on the real axis

S. O. Chaichenko

We consider the systems of rational functions ${Φ_{n} (z)}, n \in Z$ , defined by fixed set points $a := {a_{k}}_{k = 0}^{\infty}, (Im a_{k} > 0)$ , ${\bf b}:=\…
