Weighted Sobolev Spaces on Curves [PDF]

open access: yesJournal of Approximation Theory, 2002
45 pages, no figures.-- MSC1987 codes: 41A10, 46E35, 46G10. MR#: MR1934626 (2003j:46038) Zbl#: Zbl 1019.46026 In this paper we present a definition of weighted Sobolev spaces on curves and find general conditions under which the spaces are complete for non-closed compact curves. We also prove the density of the polynomials in these spaces and, finally,

Multipliers of Banach valued weighted function spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We generalize Banach valued spaces to Banach valued weighted function spaces and study the multipliers space of these spaces. We also show the relationship between multipliers and tensor product of Banach valued weighted function spaces.

Approximation by q-analogue of modified Jakimovski-Leviatan-Stancu type operators

open access: yesDemonstratio Mathematica, 2017
In this paper, we introduce the q-analogue of the Jakimovski-Leviatan type modified operators introduced by Atakut with the help of the q-Appell polynomials.We obtain some approximation results via the well-known Korovkin’s theorem for these operators.We

On the trace space of a Sobolev space with a radial weight [PDF]

open access: yesJournal of Function Spaces, 2008
Our concern in this paper lies with trace spaces for weighted Sobolev spaces, when the weight is a power of the distance to a point at the boundary. For a large range of powers we give a full description of the trace space.

Differential Transforms in Weighted Spaces

open access: yesJournal of Fourier Analysis and Applications, 2006
The authors extend the results by \textit{R. L. Jones} and \textit{J. Rosenblatt} [Math. Ann. 323, No. 3, 525--546 (2002; Zbl 1005.28012)] about the series of the differences of differential operators along lacunary sequences to BMO and to the setting of \(L^p(w)\) (the weighted \(L^p\)-spaces). Let \(\rho >1\) and let \(\{\varepsilon _k:k\in \mathbb{Z}

Volterra composition operators from generalized weighted weighted Bergman spaces to µ-Bloch spaces

open access: yesJournal of Function Spaces and Applications, 2009
Let φ be a holomorphic self-map and g be a fixed holomorphic function on the unit ball B. The boundedness and compactness of the operator Tg,φf(z)=∫01f(φ(tz))ℜg(tz)dtt from the generalized weighted Bergman space into the µ-Bloch space are studied in this
