I have a Stochastic Processes test coming up soon and we are taught about the first passage decomposition. I understand this but it then says that it changes it to a generating function

2. Relevant equations

Generating function P_{ij}(s) = Ʃ p_{ij}^{(n)}s^{n}

and F_{ij}(s) = Ʃ f_{ij}^{(n)}s^{n}

What does this generating function actually mean and what is the difference between

P_{ij}(s) and F_{ij}(s)???
