Weighted Sobolev Spaces on Curves
Journal of Approximation Theory, 2002 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, we find conditions under which the multiplication operator is bounded in the space of polynomials.

Hyponormality on a Weighted Bergman Space [PDF]
Journal of Function Spaces, 2020 A bounded Hilbert space operatorTis hyponormal ifT∗T−TT∗is a positive operator. We consider the hyponormality of Toeplitz operators on a weighted Bergman space. We find a necessary condition for hyponormality in the case of a symbol of the formf+g¯wherefandgare bounded analytic functions on the unit disk.

Differential Transforms in Weighted Spaces
Journal 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}

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

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

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

WEIGHTED MULTIRESOLUTION SPACES AND WEIGHTED WAVELETS
Electrica, 2002 In this study it is shown that the orthogonal wavelet functions will be able to got for the space sequence which gives the multiresolution spesifications in the weighted spaces for exponantial kind weighted function.

On weighted spaces without a fundamental sequence of bounded sets
International Journal of Mathematics and Mathematical Sciences, 2002 The problem of countably quasi-barrelledness of weighted spaces of continuous functions, of which there are no results in the general setting of weighted spaces, is tackled in this paper.
