On $\Delta$-Uniform and $\Delta$-Pointwise Convergence on Time Scale

Characterization of $delta$-double derivations on rings and algebras

The main purpose of this article is to offer some characterizations of $delta$-double derivations on rings and algebras. To reach this goal, we prove the following theorem:Let $n > 1$ be an integer and let $mathcal{R}$ be an $n!$-torsion free ring with the identity element $1$. Suppose that there exist two additive mappings $d,delta:Rto R$ such that $$d(x^n) =Sigma^n_{j=1} x^{n-j}d(x)x^{j-1}+Si...

On statistical type convergence in uniform spaces

The concept of ${mathscr{F}}_{st}$-fundamentality is introduced in uniform spaces, generated by some filter ${mathscr{F}}$. Its equivalence to the concept of ${mathscr{F}}$-convergence in uniform spaces is proved. This convergence generalizes many kinds of convergence, including the well-known statistical convergence.

Strong and $Delta$-convergence theorems for total asymptotically nonexpansive mappings in CAT(0)

In this work we use the Noor iteration process for total asymptotically nonexpansive mapping to establish the strong and $Delta$-convergence theorems in the framework of CAT(0) spaces. By doing this, some of the results existing in the current literature  generalize, unify and extend.

On the delta distribution: Historical remarks, Visualization of delta sequences

In this paper we present the introduction of the notion delta distribution with special accent on its historical remarks and visualization, by using programme package GeoGebra and its dynamic properties.In order to make clear and understandable the properties of delta sequences we prepared 15 Figures, with the graphs of corresponding functions, mostly given in integral forms. The Figures are ex...
