Approximation of conjugate functions by general linear operators of their Fourier series at the Lebesgue points

Wlodzimierz Lenski, Bogdan Szal

The pointwise estimates of the deviations $\widetilde{T}_{n,A,B}^{\text{}%}f\left(\cdot \right) -\widetilde{f}(\cdot)$ and $\widetilde{T}_{n,A,B}^{% \text{}}f\left(\cdot \right) -\…
