This monograph can be regarded as a result of the activity of many mathematicians of the 20th century in the field of classical Fourier series and the theory of approximation of periodic functions, beginning with H. Lebesgue, D. Jackson, and S. N. Bernstein

The purpose of this paper is to establish L^p error estimates, a Bernstein inequality, and inverse theorems for approximation by a space comprising spherical basis functions located at scattered sites on the unit n-sphere. In particular, the Bernstein inequality estimates L^p Bessel-potential Sobolev norms of functions in this space in terms of the minimal separation and the L^p norm of the function itself. An important step in its proof involves measuring the L^p stability of functions in the approximating space in terms of the l^p norm of the coefficients involved

Bernstein Inequality, Exponential Sums. This inequality is the key to proving inverse theorems for approximation by exponential sums, as we will elaborate later. Let En : ( f : f (t) a0 + n X aj e λj t, j 1 ). aj, λj ∈ R. So En is the collection of all n + 1 term exponential sums with constant first term.

Bernstein's approximation problem, posed in 1924, deals with approximation by polynomials in the weighted uniform . Nor do we discuss Saff's weighted approximation problem, nor the asymptotics of orthogonal polynomials.

Bernstein's approximation problem, posed in 1924, deals with approximation by polynomials in the weighted uniform norm fW Linfinity(R). The qualitative form of this problem was solved by Achieser, Mergelyan, and Pollard, in the 1950's. Quantitative forms of the problem were actively investigated starting from the 1960's. We survey old and recent aspects of this topic, including the Bernstein problem, weighted Jackson and Bernstein Theorems, Markov-Bernstein and Nikolskii inequalities, orthogonal expansions and Lagrange interpolation.
