# Sequential games and Perfect Bayesian Equilibrium

Reading the paper http://www.sciencedirect.com/science/article/pii/002205319190155W I came up with the following question.

Given that this paper deals with games in which players move simultaneously, the formula in (1) of Definition 3.1 makes perfectly sense. If someone considers sequential movements of the players, how Definition 3.1 (and hence formula in (1)) would change?

Any good reference about "sequential moving" games?
