| Description |
English: Boris Chirikov (1928–2008) was an outstanding Soviet and Russian physicist.
He was the founder of the physical theory of Hamiltonian chaos and made pioneering contributions to the theory of quantum chaos. In 1959, he invented the Chirikov criterion which provides an analytical estimate for the overlap of resonances (and the ensuing transition from local to global chaos) in Hamiltonian dynamical systems. |
