Some Sequence Spaces and Their Matrix Transformations
The most general linear operator to transform from new sequence space into another sequence space is actually given by an infinite matrix. In the present paper we represent some sequence spaces and give the characterization of (S (p), ) and (S (p), ).
متن کاملSome Paranormed Sequence Spaces and Matrix Transformations
Let w, γ, γo, c, co and l∞ be the spaces of all, summable, summable to zero, convergent, null and bounded sequences respectively. The notion of statistical convergence of sequences was introduced by Fast [3], Schoenberg [12] and Buck [1] independently. Later on the idea was exploited from sequence space point of view and linked with summability by Fridy [4], S̆alát [11], Kolk [5], Rath and Tripa...
متن کاملDeterminant preserving transformations on symmetric matrix spaces
Let Sn(F) be the vector space of n × n symmetric matrices over a field F (with certain restrictions on cardinality and characteristic). The transformations φ on the space which satisfy one of the following conditions: 1. det(A+ λB) = det(φ(A) + λφ(B)) for all A,B ∈ Sn(F) and λ ∈ F; 2. φ is surjective and det(A+ λB) = det(φ(A) + λφ(B)) for all A,B and two specific λ; 3. φ is additive and preserv...
متن کاملTransformations of Nested Loops with Non-Convex Iteration Spaces
When compiling for parallel machines, it is often necessary to generate a loop nest to scan a region of index points in lexicographic order. One well-known application example is the use of loop transformations to restructure loop nests. Previous work shows how to generate code to scan a convex polyhedron (possibly intersected with a lattice), a region derived from an application of a non-singu...
