Nettet23. jun. 2024 · The Lebesgue constant for a countable set of nodes provides a measure of how well the interpolant of a function at the given points compares to best polynomial approximation of the function. We are especially interested in how this constant grows with the number of interpolation nodes, i.e., the corresponding degree of the … Nettet2. feb. 2010 · There are a few assumptions that we may make without loss of generality. First, we can assume that the measure μ is nonatomic. (This follows from the fact that the atoms of μ generate an invariant sub-σ-algebra, and Theorems 4.1 and 4.2 are trivially satisfied in the case of atomic measure spaces.). Second, we can assume that the …

NettetDefines the Liminf/Limsup of a function taking values in a conditionally complete lattice, with respect to an arbitrary filter. We define Limsup f (Liminf f) where f is a filter taking values in a conditionally complete lattice. Limsup f is the smallest element a such that, eventually, u ≤ a (and vice versa for Liminf f). Nettet1. One sufficient condition is: g = ψ ∘ f where ψ: R → R is an increasing function. Indeed, in this case a sequence x n that satisfies lim f ( x n) = lim inf f also satisfies lim g ( x n) …

NettetI dag · We construct these functions by perturbing the classical recovery sequences for \(E_\varepsilon \).In particular, we need to modify the optimal one-dimensional profile \(q_0\) in such a way that the two factors in the functional \(G_\varepsilon \) concentrate in different regions, so that their product becomes small. We do this by means of a …
