Abstract

This study investigates the shape-preserving characteristics of 𝜆-Schurer operators, a class of operators derived from a modified version of the classical Schurer bases by incorporating a shape parameter 𝜆. The primary focus is on understanding how these operators maintain the geometric features of the functions they approximate, which is crucial in fields like computer graphics and geometric modelling. By examining the fundamental properties and the divided differences associated with 𝜆-Schurer bases, we derive vital results that confirm the operators’ capability to preserve essential shape attributes under various conditions. The findings have significant implications for the application of these operators in computational analysis and other related areas, providing a solid foundation for future research.

Keywords
