Mathematical classifications of the fundamental symmetries of physical systems date back to the work of Wigner, who proposed three symmetry classes of non-interacting fermionic Hamiltonians depending ...

Geometric Control Theory on Lie Groups blends control theory with differential geometry to analyse and design controllers for systems evolving on smooth manifolds that possess a group structure.

In mathematics, ubiquitous objects called groups display nearly magical powers. Though they’re defined by just a few rules, groups help illuminate an astonishing range of mysteries. They can tell you ...
