A foray into Algebraic Combinatorics

I’m trying to understand this paper by Alexander Postnikov. This post is mainly a summary of some the concepts that I do not understand. Some examples. Grassmannian- A Grassmannian of a vector space is a space that parametrizes all the dimensional subspaces of . For instance, would be . Why do we need Grassmannians?
