The time-dependent diffusion equation: An inverse diffusivity problem [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2021 We find a solution of an unknown time-dependent diffusivity a(t) in a linear inverse parabolic problem by a modified genetic algorithm. At first, it is shown that under certain conditions of data, there exists at least one solution for unknown a(t) in (a(

Fixed Point Results for Multivalued Mapping in $\mathrm{R}$-Metric Space [PDF]
Sahand Communications in Mathematical Analysis, 2023 This paper explores certain fixed point results for multivalued mapping in a metric space endowed with an arbitrary binary relation $\mathrm{R}$, briefly written as $\mathrm{R}$-metric space.

On Convex F-Contraction in b-Metric Spaces
Axioms, 2021 In this paper, we introduce a notion of convex F-contraction and establish some fixed point results for such contractions in b-metric spaces. Moreover, we give a supportive example to show that our convex F-contraction is quite different from the F ...

Fixed point theorems for rational type $F$-contraction
Karpatsʹkì Matematičnì Publìkacìï, 2021 In this paper, we consider rational type $F$-contraction for multivalued integral type mapping on a complete metric space. Using Wardowski’s technique, we establish the existence of a fixed point of the multivalued integral type mapping, if this mapping ...

Generalized $F$-contractions in Partially Ordered Metric Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2019 We discuss about the generalized $F$-contraction mappings in partially ordered metric spaces. For this, we first introduce the notion of ordered weakly $F$-contraction mapping.

Partial b-Rectangular Metric Space with Some Results
Tikrit Journal of Pure Science, 2022 A new generalization of metric space called partial b-rectangular metric space is introduced. Also, the relation between this generalization and the other generalizations for example a b-rectangular metric space is given. Moreover, we have proved Banach
