Fixed Points of E-Contraction in Controlled Metric Spaces

Shiva Verma, Manoj Ughade & Manoj Kumar Shukla · Journal of Advances in Mathematics and Computer Science · 2023

The goal of this study is to prove a fixed-point theorem for E-contraction in a completely controlled metric space. Many previous findings in the literature are extended/ generalized by our findings. We also present examples that demonstrate the utility of these findings.

Rotation without Imaginary Numbers, Transcendental Functions, or Infinite Sums

Joseph Bakhos · Journal of Advances in Mathematics and Computer Science · 2023

Quaterns are introduced as a new measure of rotation. Rotation in quaterns has an advantage in that only simple algebra is required to convert back and forth between rectangular and polar coordinates that use quaterns as the angle measure. All analogue trigonometric functions als...

Synchronizability of Generalized Two-layer Networks with Different Layer Topologies

Linfan Lian · Journal of Advances in Mathematics and Computer Science · 2023

This paper focuses on a generalized two-layer network and its synchronizability, which randomly generate different topologies at each layer. This kind of network can better describe some irregular networks in reality. From the master stability function method of network synchroni...
