Banach-Mazur Distance Between Two Dimensional Banach Spaces

Sarajevo Journal of Mathematics
The purpose of the present paper is to investigate geometric properties of two-dimensional Banach spaces. We are also concerned with the Banach-Mazur distance between Banach spaces.

Some Results about Completion of the Space of Henstock-Kurzweil Integrable Functions

, 2014
Continuing with our study begun in [6] and making use of some results of that article, in this paper we establish new properties for the completion of the space of Henstock-Kurzweil integrable functions with Alexiewicz norm.

Approximate derivations on Banach algebras associated with Jensen functional equation

, 2013
In this paper, we examine the generalized Hyers–Ulam stability of derivations associated with the Jensen functional equation f ( x − y n + z ) + f ( y − z n + x ) + f ( z − x n + y ) = f(x) + f(y) + f(z) on Banach algebras for any fixed nonzero integer n.
