What is the author's style in Top Girls by Caryl Churchill?

Top Girls is not a linear play, but one in which time is used in an unusual fashion. The last scene of the play, act 2, scene 2, is the only part that takes place at a specific time in the story, about a year earlier than the other events. This flashback ties up some of the loose ends created by the story. The rest of the scenes, even the action within act 2, scene 1, do not have to take place in the order presented, though all are set in the present. The events are linked thematically, but not by a specific sequence of time. In addition, the idea of time is toyed with at the dinner party in act 1, scene 1. None of the guests can really exist at the same time, yet they share many of the same concerns.
