Approximation of generalized Poisson integrals by interpolating trigonometric polynomials

UDC 517.5 We establish asymptotically unimprovable interpolation analogs of Lebesgue-type inequalities for $2\pi$-periodic functions $f$ that can be represented in the form of generalized Poisson integrals of&nbsp; functions $\varphi$ from the space $L_p,$ $1\leq p\leq \infty.$&nbsp;...
