Iterates of q-Bernstein operators on triangular domain with all curved sides

Iliyas Mohammad, Khan Asif, Arif Mohd, Mursaleen Mohammad, Lone Mudassir Rashid

Demonstratio Mathematica

2022

Vol. 55, nr 1

891-899

In this article, Phillips-type Bernstein operators (Btm,qF)(t,s) and (Bsn,qF)(t,s) , their products, and Boolean sum based on q-integer have been studied on a triangle with all curved sides. Furthermore, convergence of iterates of these operators have been analyzed using the weakly Picard operators technique and the contraction principle.

A fixed point theorem for multi-valued weakly Picard operators in b-metric space

Olatinwo M.

Demonstratio Mathematica

2009

Vol. 42, nr 3

599-606

In this paper, we establish a fixed point theorem for multi-valued operators in a complete b-metric space using the concept of Berinde and Berinde [9] on multi-valued weak contractions for the Picard iteration in a metric space. Our main result generalizes, extends and improves some of the recent results of Berinde and Berinde [9] as well as those of Daffer and Kaneko [17] and also unifies several classical results pertainning to single and multi-valued contractive mappings in the literature.

Selections and common fixed points for some generalized multivalued contractions

Sintamarian A.

Demonstratio Mathematica

2006

Vol. 39, nr 3

609-617

We show that some generalized multivalued contractions admit selections which are Caristi type mappings. Another purpose of this paper is to give a common fixed point theorem for two multivalued contractive type mappings defined on a closed ball of a complete metric space with values in the set of all nonempty and closed subsets of this space.
