Best Approximations in the Spaces , and , 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.

Classes of Periodic Functions,tions, . is a fixed operator acting from . into Φ, Φ. is a set of functions ϕ∈Φ satisfyingthe condition ., and .is the preimage of Φ. under the mapping .:.(.)=Φ.. Then the set . is called a class of functions . such that .(.) = ϕ ∈ Φ..

The Referents of Musichis reason, can hardly serve a moral or political purpose. This brief discussion is intended to demonstrate just how non-referential music is and why, at the same time, we tend to ascribe more precise reference to it than it, intrinsically, has.
