Reports of China’s Basic Research In these spaces, unlike the spaces ., 1 < . < ∞, in the general case, the approximation by Fourier sums no longer has the order of the best approximation. Moreover, as was already noted, the space . contains functions whose Fourier series diverge.

Poverty-Alleviation and Social Work in China is a polynomial, then the value δ.(.) can often be represented as a convolution where the function ϕ depends only on ., and the kernel Φ. depends only on a method of constructing operators .(.). This forms a basis of one of the most widely used and efficient approaches to studying the value δ.(x),
