Geoff is unpopular with the rest of the Frontline staff to the point where he is banned from the Frontline set, but they are all supportive when he unexpectedly achieves popularity with his own one-hour programme in Addicted to Fame ( series 3 ), though he is unaware that Mike demanded the plans for the expansion of the show be cancelled because he was jealous of the attention Geoff was getting.

The number of times the interaction Hamiltonian acts is the order of the perturbation expansion, and the time-dependent perturbation theory for fields is known as the Dyson series.
