In this paper, we introduce a generalization of Hilbert $C^*$-modules which are pre-Finsler modules, namely, $C^{*}$-semi-inner product spaces. Some properties and results of such spaces are investigated, specially the orthogonality in these spaces w

$K$-frames as a generalization of frames were introduced by L. Gu{a}vruc{t}a to study atomic systems on Hilbert spaces which allows, in a stable way, to reconstruct elements from the range of the bounded linear operator $K$ in a Hilbert space. Recent

In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopolog

Suppose that 𝑋 is a Banach space and 𝐶 is an injective operator in 𝐵(𝑋), the space of all bounded linear operators on 𝑋. In this note, a two-parameter 𝐶-semigroup (regularized semigroup) of operators is introduced, and some of its p

Let H be a compact subgroup of a locally compact group G. In this paper we define a convolution on M(G/H) , the space of all bounded complex Radon measures on the homogeneous space G/H. Then we prove that the measure space M(G/H) with the newly well-

Let $$\alpha $$ be a topological automorphism on a locally compact abelian group G, satisfies $$\alpha (p^{2})=p$$ for all $$p\in G$$ . This paper deals with defining Fourier–Wigner, Wigner and Weyl transforms with respect to $$\alpha $$ , and amon

In this paper, we define the wavelet multiplier and Landau–Pollak–Slepian (L.P.S) operators on the Hilbert space $$L^2(G)$$ , where G is a locally compact abelian topological group and investigate some of their properties. In particular, we show
