Weighted approximation by triginometric sums and the Carleman-Golusin-Krylov formula
Autor: V. P. Khavin, V. A. Bart
Publikováno v: Journal of Mathematical Sciences. 80:1873-1879
An explicit formula is given yielding linear combinations of harmonics with negative frequencies approximating a prescribed harmonic with a positive frequency in a weighted space L2(h). The formula is based on the Carleman-Krylov-Goluzin interpolatio

Szeg�-Kolmogorov-Krein theorems on weighted trigonometrical approximation and C�rleman-type relations
Autor: V. A. Bart, V. P. Khavin
Publikováno v: Ukrainian Mathematical Journal. 46:101-132
We consider the well-known Szego — Kolmogorov — Krein theorems on weighted approximations by functions with semibounded spectra defined on a circle or on a line and suggest an efficient construction that realizes these approximations. This constr

Poisson kernel is the unique approximate identity, asymptotically multiplicative on H?
Autor: Kh. Vol'f, V. P. Khavin
Publikováno v: Journal of Soviet Mathematics. 63:159-163
Let\(\varphi \in L^1 (\mathbb{R}), \mathfrak{J}\mathfrak{m} \varphi = 0, \int \varphi = 1, \mathop {lim}\limits_{\varepsilon \to 0} ||(\varphi _\varepsilon *f)^2 - \varphi _\varepsilon *(f^2 )||_\infty = 0\) for anyf ∈ H∞(R), where ϕ e (x): =e

Methods and Structure of Commutative Harmonic Analysis
Autor: V. P. Khavin
Publikováno v: Commutative Harmonic Analysis I ISBN: 9783642057397
Many really significant “final” scientific achievements share the following two characteristics. First of all, they are sufficiently trivial, and, hence, can become of “common use”, i.e., necessary and conventional. Yet, by “conventional”
