Translation, modulation and dilation systems in set-valued signal processing
Journal Title: Карпатські математичні публікації - Year 2018, Vol 10, Issue 1
Abstract
In this paper, we investigate a very important function space consists of set-valued functions defined on the set of real numbers with values on the space of all compact-convex subsets of complex numbers for which the pth power of their norm is integrable. In general, this space is denoted by Lp for 1≤p<∞ and it has an algebraic structure named as a quasilinear space which is a generalization of a classical linear space. Further, we introduce an inner-product (set-valued inner product) on L2(R,Ω(C)) and we think it is especially important to manage interval-valued data and interval-based signal processing. This also can be used in imprecise expectations. The definition of inner-product on L2(R,Ω(C)) is based on Aumann integral which is ready for use integration of set-valued functions and we show that the space L2(R,Ω(C)) is a Hilbert quasilinear space. Finally, we give translation, modulation and dilation operators which are three fundational set-valued operators on Hilbert quasilinear space L2(R,Ω(C)).

In this paper, we investigate the convergence of multidimensional S-fractions with independent variables, which are a multidimensional generalization of S-fractions. These branched continued fractions are an efficient to...

In this paper, we consider a generalization almost Kenmotsu f-manifolds. We get basic Riemannian curvature, sectional curvatures and scalar curvature properties such type manifolds. Finally, we give two examples to clari...
Homomorphisms and functional calculus in algebras of entire functions on Banach spaces
In the paper the homomorphisms of algebras of entire functions on Banach spaces to a commutative Banach algebra are studied. In particular, it is proposed a method of constructing of homomorphisms vanishing on homogeneou...
On the similarity of matrices AB and BA over a field
Let A and B be n-by-n matrices over a field. The study of the relationship between the products of matrices AB and BA has a long history. It is well-known that AB and BA have equal characteristic polynomials (and, theref...
