Linearization in Certain Nonconvex Minimization Problems and Generalized Spline Projectionstor constraints on f, leads directly to the consideration of constrained nonconvex minimization problems in a Hilbert space and, more generally, in a Banach space. In and an existence and convergence theory was developed for the solutions of extremal problems of the form . where T is a (poss

Averaging Interpolation that is, that minimizes the deviation δ(f,P) defined by the ρ. power metric (1 < ρ < ∞) with positive weights or (ρ = ∞) by max {f − P} on X, and there are at least n + 1 points on X, where the difference f − P takes alternatingly positive and negative values. When N = n the polynomial P. is the po

Splines and Histogramslation. Moreover, and this is an important point, the data are not the usual function values that are to be interpolated, but rather approximations of the derivative (i.e. the unknown density function) in the form of a histogram. This (pershaps only apparent) difference is bridged by the ingenious a

Stability Properties of Trigonometric Interpolation Operators fixed, and the spaces are endowed with the usual supremum norm. Any operator L: C → π which can be written in the form . with 0 ≤ s. < 2≤ and y. ε π is said to be . by the point set {s.,...,s.}. If Lx = x for all x ε π, then L is a . of C onto π. The . is defined to be the set of points t. = kπ(2n

Saturation and Inverse Theorems for Spline Approximationline approximation in terms of the smoothness of the function. Estimates like this are customarily called direct theorems of approximation. Our main interest lies in the opposite direction, i.e., what inferences can be made about the smoothness of a function when its degree of approximation is known.
