Quantum systems with finite Hilbert space are considered. Position and mo- mentum states and their relation through a Fourier transform, displacement in the position-momentum phase-space, and symplectic transformations are introduced and their properties are studied. Symplectic …

The historical global surface temperature (GST) exhibits staircase-like evolutions with both accelerated warming periods and warming slowdown periods. The rate of GST change slowed down during 2003-2012, relative to the warming acceleration in the late 20th century and is termed…
