Functions universal with respect to the trigonometric system
M. G. Grigoryan, L. N. Galoyan Yerevan State University
Abstract:
We construct an integrable function whose Fourier series possesses the following property. After an appropriate
choice of signs of the coefficients of this series, the partial sums of the resulting series are dense in $L^p$, $p\in(0,1)$.
Keywords:
universal function, universal trigonometric series, Fourier series, convergence in $L^p$.
