development through the definitions and comparison of weaker forms of continuity notions in …

An Extended Kannan Contraction Map** and Applications

RP Pant - International Journal of Mathematical, Engineering …, 2024 - search.proquest.com
We extend the Kannan contraction principle and obtain a result that holds for both
contractive and non-expansive map**s. Such map**s admit multiple fixed-points and …

A general fixed point theorem

RP Pant, V Rakočević, D Gopal, A Pant, M Ram - Filomat, 2021 - doiserbia.nb.rs
In this paper we prove a theorem which ensures the existence of a unique fixed point and is
applicable to contractive type map**s as well as map**s which do not satisfy any …

[PDF][PDF] On two new contractions and discontinuity on fixed points

M Zhou, N Saleem, XL Liu, N Özgür - AIMS Math, 2022 - aimspress.com
This paper deals with a well known open problem raised by Kannan (Bull. Calcutta Math.
Soc., 60: 71–76, 1968) and BE Rhoades (Contemp. Math., 72: 233–245, 1988) on the …

Fixed point and periodic point theorems

RP Pant, V Rakočević - Acta Scientiarum Mathematicarum, 2024 - Springer
We introduce a weaker form of continuity which is a necessary and sufficient condition for
the existence of fixed points. The obtained theorems exhibit interesting fixed point–eventual …

On the geometry of fixed points and discontinuity

Recently, there has been a considerable effort to obtain new solutions to the Rhoades' open
problem on the existence of contractive map**s that admit discontinuity at the fixed point …

Extended Φ-contraction map**s

RP Pant - The Journal of Analysis, 2024 - Springer
We extend the concept of Φ-contraction map**s and introduce a condition that applies to
contraction map**s as well as nonexpansive map**s. The fixed-point sets and domains …

New Answers to the Rhoades' Open Problem and the Fixed-Circle Problem

N Taş - Conference Proceedings of Science and Technology, 2020 - dergipark.org.tr
Recently, the Rhoades' open problem which is related to the discontinuity at fixed point of a
self-map** and the fixed-circle problem which is related to the geometric meaning of the …

Fixed ellipse theorems in metric spaces and an application of discontinuous activation function in neural networks

T Ermiş, G Zaim Erçınar… - Mathematical Methods in …, 2023 - Wiley Online Library
In this article, we establish new fixed ellipse theorems that will provide a geometrical
perspective to the classical metric fixed point theory. Also, we provide novel fixed ellipse …

FIXED POINT SETS OF SELF-MAPPINGS WITH A GEOMETRIC VIEWPOINT

U Çelik, N Özgür - Facta Universitatis, Series: Mathematics …, 2022 - casopisi.junis.ni.ac.rs
In this paper, we obtain new fixed point results with the help of various techniques
constructed by using auxiliary numbers and some family of functions. In the context of the …
