Testing Weyl geometric gravity with the SPARC galactic rotation curves database

2 years ago

Abstract We present a detailed investigation of the properties of the galactic rotation curves in the Weyl geometric gravity model, in which…

On the iterates of uni- and multidimensional operators

2 years ago

Abstract The problem of the convergence of the iterates of operators or of a sequence of operators is discussed in…

Păltănea’s operators: old and new results

2 years ago

Abstract This note concerns the study of an approximation linear positive process introduced by R. Paltanea in 2008. Considering the…

Role of partial functionals in the study of variational systems

2 years ago

Abstract Applying techniques originally developed for systems lacking a variational structure, we establish conditions for the existence of solutions in…

New Subclasses of Univalent Mappings in Several Complex Variables: Extension Operators and Applications

2 years ago

Abstract In this paper we define new subclasses of univalent mappings in the case of several complex variables. We will…

A method of lower and upper solutions for control problems and application to a model of bone marrow transplantation

2 years ago

Abstract A lower and upper solution method is introduced for control problems related to abstract operator equations. The method is…

Existence Results for Some Functional Integrodifferential Equations with State-Dependent Delay

Abstract In this work, we establish sufficient conditions for the existence of solutions for some functional integrodifferential equations with state-dependent…

Iterative Shepard operator of least squares thin-plate spline type

3 years ago

AbstractWe propose a modified bivariate Shepard operator of least squares thin-plate spline type based on an iterative method, introduced by…

The strict superlinear order can be faster than the infinite order

3 years ago

Abstract The strict superlinear order (superlinear convergence) was usually regarded as having an intermediate speed between between linear and with…

Dinkelbach Type Approximation Algorithms for Nonlinear Fractional Optimization Problems
