Lebesgue points and Cesàro summability of higher dimensional Fourier series over a cone
We introduce a new concept of Lebesgue points, the so-called ωLebesgue points, where ω > 0. As a generalization of the classical Lebesgue’s theorem, we prove that the Cesàro means σ a nf of the Fourier series of a multidimensional function f ∈ L1(T d ) converge to f at each ω-Lebesgue point (0 &l...
