AbstractLet C(n) (I) denote the Banach space of n-times continuously differentiable functions on I = [0, 1], equipped with the norm ||f||n = max { |f(0)|, |fʹ(0)|, … , |f(n–1)(0)|, ||f(n)||∞} (f ) ∈… Continue Reading

The main purpose of this paper is to characterize norm-additive in modulus, not necessarily linear, maps defined between function algebras (not necessarily unital or uniformly closed). In fact, for… Continue Reading

In this paper, we describe into real-linear isometries defined between (not necessarily unital) function algebras and show, based on an example, that this type of isometries behaves differently from… Continue Reading

Let $$A_1, \ldots , A_k$$A1,…,Ak be function algebras (or more generally, dense subspaces of uniformly closed function algebras) on locally compact Hausdorff spaces $$X_1, \ldots ,X_k$$X1,…,Xk,… Continue Reading

Let denote by Fk,n the n k-Fibonacci number where Fk,n = kFk,n−1+ Fk,n−2 for n ≥ 2 with initial conditions Fk,0 = 0, Fk,1 = 1, we may derive a functional equation f(k, x) = kf(k, x − 1) + f(k, x −… Continue Reading

In this paper we deal with the algebraic reflexivity of sets of bounded linear operators on absolutely continuous vector-valued function spaces. As a consequence, it is shown that the set of all… Continue Reading
