Continuous $k$-Fusion Frames in Hilbert Spaces [PDF]

Sahand Communications in Mathematical Analysis, 2020
The study of the c$k$-fusions frames shows that the emphasis on the measure spaces introduces a new idea, although some similar properties with the discrete case are raised. Moreover, due to the nature of measure spaces, we have to use new techniques for

Dual Transformations in Galilean Spaces

International Electronic Journal of Geometry, 2020
In this study, we define a dual transformation between $G^{n}$ and $G^{n}_{1}$. We examine the invariance of the plane where the shear motion is acting in Galilean and pseudo-Galilean spaces. We define a dual transformation between $\widehat{G^{n}}$ and $\widehat{G^{n}_{1}}$ as well. We provide applications in $G^{3}$ and $G^{3}_{1}$.

Pre-Dual of Fofana’s Spaces

Mathematics, 2019
The purpose of this paper is to characterize the pre-dual of the spaces introduced by I. Fofana on the basis of Wiener amalgam spaces. These spaces have a specific dilation behaviour similar to the spaces L α ( R d ) .

A Study of Spaces of Sequences in Fuzzy Normed Spaces

Mathematics, 2021
In this paper, spaces of sequences in fuzzy normed spaces are considered. These spaces are a new concept in fuzzy normed spaces. We develop fuzzy norms for spaces of sequences in fuzzy normed spaces. Especially, we study the representation of the dual of

G3-homogeneous gravitational instantons [PDF]

, 2009
We provide an exhaustive classification of self-dual four-dimensional gravitational instantons foliated with three-dimensional homogeneous spaces, i.e.

A Study of Approximation Properties in Felbin-Fuzzy Normed Spaces

Mathematics, 2020
In this paper, approximation properties in Felbin-fuzzy normed spaces are studied. These approximation properties have been recently introduced in Felbin-fuzzy normed spaces. We make topological tools to analyze such approximation properties.

New results on q-positivity [PDF]

, 2011
In this paper we discuss symmetrically self-dual spaces, which are simply real vector spaces with a symmetric bilinear form. Certain subsets of the space will be called q-positive, where q is the quadratic form induced by the original bilinear form.

Separable dual-space Gaussian pseudopotentials [PDF]

Physical Review B, 1996
We present pseudo-potential coefficients for the first two rows of the periodic table. The pseudo potential is of a novel analytic form, that gives optimal efficiency in numerical calculations using plane waves as basis set. At most 7 coefficients are necessary to specify its analytic form.

Mass, Entropy and Holography in Asymptotically de Sitter Spaces [PDF]

, 2001
We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity.
