The ham sandwich theorem, demonstrated by mathematicians AH Stone and J. Tukey in 1942, tells us that if we want ...
Abstract: The existence of surface waves on anisotropic materials was proven under fairly general conditions by Lothe and Barnett in 1976. But, until now, the status of surface waves on piezoelectric ...
Self-driving cars, autonomous robots, modern airplanes, or robotic surgery: we increasingly entrust our lives to computers and therefore should strive for nothing but the highest safety standards - ...
Abstract: An optimal power flow (OPF) problem can have one or multiple locally optimal solutions. It can also admit no solution. Few studies have addressed the existence of OPF solutions and derived a ...
ABSTRACT: In this paper, we consider a class of damped vibration systems with super-quadratic potential. We obtain at least two nonzero periodic solutions through the minimization method and Morse ...
With the introduction of mathematics into biological research, patterns arising from biological problems can be effectively studied. The complex interactions involving biological systems and invading ...
Department of Mathematics, Northwest Normal University, Lanzhou, China. The boundary value problems of the third-order ordinary differential equation have many practical application backgrounds. They ...
The main results of this note were presented by the writer in a 15-minute talk at the International Congress of Mathematicians in Edinburgh, August, 1958. They were obtained while the writer held a ...
