We consider the rotation set $\rho(F)$ for a lift $F$ of a homeomorphism $f: T^2 \rightarrow T^2$, which is homotopic to the identity. Our main result is that if a ...

A trio of physicists from Princeton University, CIT's Jet Propulsion Laboratory and Spectral Sensor Solutions, all in the U.S., is proposing the possibility of generating electricity using energy from ...

A team of scientists has developed a novel way to measure variations in the Earth's rotation. In their paper published in the journal Nature Photonics, the team explains how their new approach works ...
