Electromagnetism and Gravitation: A Conformal Jigsaw Puzzle ()

We also prove that the two sets of Maxwell equations only depend on the non-linear elations of the conformal group of space-time when n = 4 by using the Spencer δ-cohomology that has only been ...

Adaptive Prescribed-Time Output Tracking of Clustered Uncertain Euler-Lagrange Systems: A Predefined-Track Containment Control Method

Abstract: In this article, a novel general clustered network framework with hybrid communication is constructed for multiple uncertain Euler-Lagrange (EL) systems. The objective is to ensure that the ...

Predictor-based Safety-Critical Formation Control of Switched Uncertain Euler-Lagrange Systems

Abstract: This paper presents a predictor-based safety-critical formation control method for multiple Euler-Lagrange systems with safety constraints, as well as model uncertainties. The communication ...
