Uniformly convex and strictly convex Orlicz spaces [PDF]

open access: bronzeAIP Conference Proceedings, 2016
In this paper we define the new norm of Orlicz spaces on ℝn through a multiplication operator on an old Orlicz spaces. We obtain some necessary and sufficient conditions that the new norm to be a uniformly convex and strictly convex spaces.

ON UNIFORMLY CONVEX AND UNIFORMLY 2-CONVEX 2-NORMED SPACES [PDF]

open access: hybridDemonstratio Mathematica, 1992
The author starts with the definition of two-norm on a linear space of dimension greater than 1 and defines a uniformly convex 2-normed space extending the definition of J. A. Clarkson. Theorems 1-5 and some corollaries are established on uniformly convex and uniformly 2-convex 2- normed spaces.

A uniformly convex hereditarily indecomposable Banach space [PDF]

open access: greenIsrael Journal of Mathematics, 1995
A {\em hereditarily indecomposable (or H.I.)} Banach space is an infinite dimensional Banach space such that no subspace can be written as the topological sum of two infinite dimensional subspaces. As an easy consequence, no such space can contain an unconditional basic sequence.

Constructive reflexivity of a uniformly convex Banach space [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1988
In this paper we consider a question about reflexivity of a Banach space within the framework of Bishop’s constructive mathematics and we give a partially affirmative answer to the question set by Bishop: "Is every uniformly convex Banach space reflexive?".

Continuity of extremal elements in uniformly convex spaces [PDF]

open access: bronzeProceedings of the American Mathematical Society, 2009
In this paper, we study the problem of finding the extremal element for a linear functional over a uniformly convex Banach space. We show that a unique extremal element exists and depends continuously on the linear functional, and vice versa. Using this, we simplify and clarify Ryabykh's proof that for any linear functional on a uniformly convex ...

Strict Convexity and Uniform Convexity in Linear 2-normed Spaces

open access: yesJournal of Harbin University of Science and Technology, 2021
Linear 2-normed space is a generalization of linear normed space, which defines a more extensive norm. In this paper, we get contraction mapping theorem in linear 2-normed space holds, and the set of fixed points for nonexpansive mapping is convex when ...

Fixed point theorems in uniformly convex Banach spaces

open access: yesRatio Mathematica, 2023
In this article, we establish a concept of fixed point result in Uniformly convex Banach space. Our main finding uses the Ishikawa iteration technique in uniformly convex Banach space to demonstrate strong convergence.

UNIFORMLY CONVEX-TRANSITIVE FUNCTION SPACES [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2009
We introduce a property of Banach spaces called uniform convex-transitivity, which falls between almost transitivity and convex-transitivity. We will provide examples of uniformly convex-transitive spaces. This property behaves nicely in connection with some Banach-valued function spaces.

The generalized projection methods in countably normed spaces

open access: yesJournal of Inequalities and Applications, 2021
Let E be a Banach space with dual space E ∗ $E^{*}$ , and let K be a nonempty, closed, and convex subset of E. We generalize the concept of generalized projection operator “ Π K : E → K $\Pi _{K}: E \rightarrow K$ ” from uniformly convex uniformly smooth

Convergence Theorems for an Iteration of Non-Lipschitzian Nonself Mappings in Banach Spaces

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2021
In this study,a new iteration with errors for non-Lipschitzian nonself mappings in the uniformly convex Banach space is introduced.The convergence of such iteration is investigated and which proves that if the uniformly convex Banach space X satisfies ...
