Boundedness of localization operators on Lorentz mixed-normed modulation spaces
Sandikci, Ayse (Springer, 2014)In this work we study certain boundedness properties for localization operators on Lorentz mixed-normed modulation spaces, when the operator symbols belong to appropriate modulation spaces, Wiener amalgam spaces, and Lorentz ... -
Continuity of Wigner-type operators on Lorentz spaces and Lorentz mixed normed modulation spaces
Sandikci, Ayse (Scientific Technical Research Council Turkey-Tubitak, 2014)We study various continuity properties for tau-Wigner transform on Lorentz spaces and tau-Weyl operators W-tau(a) with symbols belonging to appropriate Lorentz spaces. We also study the action of tau-Wigner transform on ... -
GABOR ANALYSIS OF THE SPACES M (p, q, w) (R-d) AND S (p, q, r, w, omega) (R-d)
Sandikci, Ayse; Gurkanli, A. Turan (Springer, 2011)Let g be a non-zero rapidly decreasing function and w be a weight function. In this article in analog to modulation space, we define the space M(p, q, w)(R-d) to be the subspace of tempered distributions f E S'(R-d) such ... -
Generalized Sobolev-Shubin spaces, boundedness and Schatten class properties of Toeplitz operators
Sandikci, Ayse; Gurkanli, Ahmet Turan (Scientific Technical Research Council Turkey-Tubitak, 2013)Let w and omega be two weight functions on R-2d and 1 <= p, q <= infinity. Also let M (p, q, omega) (R-d) denote the subspace of tempered distributions S' (R-d) consisting of f is an element of S' (R-d) such that the Gabor ... -
Multilinear tau-Wigner transform
Sandikci, Ayse (Springer Basel Ag, 9999)In this work, we introduce a tau-dependent multilinear Wigner transform W-tau, tau is an element of [0, 1](d). It also includes various types of multilinear time-frequency representations, among the others the classical ... -
On function spaces with fractional Fourier transform in weighted Lebesgue spaces
Toksoy, Erdem; Sandikci, Ayse (Springer International Publishing Ag, 2015)Let w and co be weight functions on R-d. In this work, we define A(alpha,p)(w,omega)(R-d) to be the vector space of f is an element of L-w(1) (R-d) such that the fractional Fourier transform F(alpha)f belongs to L-omega(p)(R-d) ... -
On Lorentz mixed normed modulation spaces
Sandikci, Ayse (Springer Basel Ag, 2012)This paper is a study on a new kind modulation spaces M(P, Q)(R-d) and A(P, Q, r)(R-d) for indices in the range 1 < P < infinity, 1 <= Q < infinity and 1 <= r < infinity, modelled on Lorentz mixed norm spaces instead of ... -
On the Inclusions of Some Lorentz Mixed Normed Spaces and Wiener-Ditkin Sets
Sandikci, Ayse (Univ Prishtines, 2018)In this paper, we consider sufficient and necessary condition for the inclusion between Lorentz spaces with mixed norms for two different product measures on (X x Y; A x B) : Later, we discuss the Wiener-Ditkin sets of ... -
The spaces of bilinear multipliers of weighted Lorentz type modulation spaces
Gurkanli, Ahmet Turan; Kulak, Oznur; Sandikci, Ayse (Walter De Gruyter Gmbh, 2016)Fix a nonzero window g is an element of S(IRn), a weight function w on R-2n and 1 <= p, q <= infinity. The weighted Lorentz type modulation space M(p, q, w)(R-n) consists of all tempered distributions f is an element of ...
