You can find a pdf copy of the 2nd edition of EC1 here. We will first review basic enumerative combinatorics in chapter 1, and then cover topics on integral polytopes and Ehrhart theory. We will finish with parts of chapter 3 in EC1. Reference for material on Ehrhart theory: Compute the Continuous Discretely: Integer-point Enumeration in Polyhedra, by Matthias Beck and Sinai Robins. A pdf version of the second edition is available on here. Lectures on Polytopes, by Günter Ziegler. Integer Points in Polyhedra, by Alexander Barvinok. Homework Homework will be assigned on the homework webpage, and collected in the class on the due date. You will have at least one week between the homework is posted and the due date.
