One-Sided Approximation of Functions
where :Yl denotes the orthogonal complement of Y (see [I]). Another example of this type of duality appears in one of the classical moment problems. Letfbe Bore1 measurable and bounded on [a,b], h,, . . ., h, a CebySev system on [a,b] and for a given positive Bore1 measure yO defined on [a,b] denote by C (y,,) the class of all positive Bore1 measures y which satisfy f.bhkdy=[hkdyo k= 1,2 ,..., ...
متن کاملOne-sided approximation by entire functions
Let f : R→ R have an nth derivative of finite variation Vf(n) and a locally absolutely continuous (n− 1)st derivative. Denote by E±(f, δ)p the error of onesided approximation of f (from above and below, respectively) by entire functions of exponential type δ > 0 in Lp(R)–norm. For 1 ≤ p ≤ ∞ we show the estimate E±(f, δ)p ≤ C n π1/pVf(n)δ −n− 1 p , with constants Cn > 0.
متن کاملComputation of Best One - Sided Lx Approximation
A computational procedure based on linear programming is presented for finding the best one-sided Li approximation to a given function. A theorem which ensures that the computational procedure yields approximations which converge to the best approximation is proved. Some numerical examples are discussed.

متن کاملOne - Sided L ’ Approximation by Splines with Fixed Knots
The purpose of this note is to indicate how the methods of Galkin [2], and Bojanic and DeVore [I] may be extended to a consideration of the problem of one-sided L1 approximation by splines with fixed knots. This paper also supplements the cases considered by Micchelli and Pinkus [7], and Micchelli [6], where the function which was approximated, both in the oneand twosided sense, was contained i...
