Fixed Points Results for α-Admissible Mapping of Integral Type on Generalized Metric Spaces

Abstract and Applied Analysis, 2015
We introduce generalized (α,ψ)-contractive mappings of integral type in the context of generalized metric spaces. The results of this paper generalize and improve several results on the topic in literature.

Integral points of bounded height on a log Fano threefold

, 2019
We determine an asymptotic formula for the number of integral points of bounded height on a blow-up of $\mathbb{P}^3$ outside certain planes using universal torsors.Comment: 18 ...

Weak ψ-Contractions on Directed Graphs with Applications to Integral Equations

Mathematics
This article deals with a few outcomes ensuring the fixed points of a weak (G,ψ)-contraction map of metric spaces comprised with a reflexive and transitive digraph G. To validate our findings, we furnish several examples. The findings we obtain enable us

Stable integration rules with scattered integration points

Journal of Computational and Applied Mathematics, 1999
The author proposes a general method for functional approximation applied to produce stable multidimensional integration rules. Integration formulas with scattered nodes are constructed to be exact for a quasi-uniform distribution of the integration points. Numerical results on scattered data integration rules in 2-D and 3-D are included.

Theoretical Analysis of Nonparametric Filament Estimation

, 2015
This paper provides a rigorous study of the nonparametric estimation of filaments or ridge lines of a probability density $f$. Points on the filament are considered as local extrema of the density when traversing the support of $f$ along the integral ...

Integral points and volume of integral-integral affine manifolds

We give an elementary proof that, for a closed manifold with an integral-integral affine structure, its total volume and number of integral points coincide. The proof uses rational Ehrhart theory and elementary Fourier analysis to estimate the difference between the total volume and the number of integral points.

Fixed points for alpha-psi contractive mappings with an application to quadratic integral equations

Electronic Journal of Differential Equations, 2014
Recently, Samet et al [24] introduced the concept of alpha-psi contractive mappings and studied the existence of fixed points for such mappings. In this article, we prove three fixed point theorems for this class of operators in complete metric ...
