Web1 Jul 2014 · The notion of sliding window methods for measurable real-valued functions in the interval [0,∞) is presented, and a series of theorems along with examples via summability methods are established. Expand WebThe summability method ρ defines a natural summability method on the dual of a normed space X, we say that a sequence (f j) ⊂ X ∗ is said to be w ∗ ρ convergent to f ∈ X ∗ (in brief f k w ∗ ρ f) if for any x ∈ X we have that f j (x) ρ f (x). Thus ρ …

Web11 Oct 2024 · A regular matrix summability method is a matrix transformation of a convergent sequence which preserves the limit. It is well-known that the Silverman-Toeplitz theorem characterizes the regularity of a matrix summability method (see [8, 26]). Throughout the paper, we will consider \(A=[a_{jn}]\) as a nonnegative regular … WebIn mathematics and theoretical physics, zeta function regularization is a type of regularization or summability method that assigns finite values to divergent sums or … my ashley world ultipro login
