The equation of time is the difference between the apparent (sun observed) time and the modern day uniform time. This paper explains what causes the Equation of Time to arise. It is shown that it ...
Abstract: It is noteworthy that the Sylvester equation plays a pivotal role in the field of industrial intelligence control. To meet the demands of real-time applications, temporal-dependent Sylvester ...
In four-dimensional asymptotically flat spacetimes, an infinite tower of soft graviton modes generates the symmetry algebra of w(1+infinity) at tree level. This algebra is a universal feature of ...
