This volume includes new topics such as the stochastic limit approach to nonequilibrium states, a new algebraic approach to relativistic nonequilibrium local states, classical and quantum features of weak chaos, transports in quantum billiards, the Welcher–Weg puzzle with a decaying atom, and the topics related to the quantum Zeno effect.
