Fixed Points of Expansive Type Mappings in 2-Banach Spaces

open access: yesInternational Journal of Analysis and Applications, 2013
In present paper, we define expansive mappings in 2-Banach space and prove some common unique fixed point theorems which are the extension of results of Wang et al. [12] and Rhoades [9] in 2-Banach space.

On Small Combination of Slices in Banach Spaces

open access: yesExtracta Mathematicae, 2016
The notion of Small Combination of Slices (SCS) in the unit ball of a Banach space was first introduced in [4] and subsequently analyzed in detail in [12] and [13].

On Subspaces of Indecomposable Banach Spaces [PDF]

open access: yesarXiv
We address the following question: what is the class of Banach spaces isomorphic to subspaces of indecomposable Banach spaces? We show that this class includes all Banach spaces of density not bigger than the continuum which do not admit $\ell_\infty$ as a quotient (equivalently do not admit a subspace isomorphic to $\ell_1(\cc)$).
