Because there is no ozone radiative feedback in either simulation, the dynamical evolutions are identical, and therefore differences are due entirely to the changes in chemistry.

In late 1960s and early 1970s he was involved in dynamical evolution of star clusters, in particular the globular clusters.

The wavefunction itself, and not the particles, determines the dynamical evolution of the system: the particles do not act back onto the wave function.

In Cosmology the term Back-reaction is used for the measure of the non commutativity of the averaging procedure and the dynamical evolution of space-time.

Under these conditions, the dynamical evolution within , where is the system Hilbert space, is completely unitary (all possible bath states) if and only if:

Therefore, any state in will not decohere since its evolution is governed by a unitary operator and so its dynamical evolution will be completely unitary.

Note that when , the dynamical evolution of the system is unitary.

He places the current material World in this entropic, dynamical evolution of the energy-matter-information equilibrium.

He has been involved in investigations on small bodies in the solar system using optical telescopes, meteor radar systems, and theoretical techniques to investigate their dynamical evolution.

Direct N-body simulations are used to study the dynamical evolution of star clusters.
