Schedule
During September and October we will be following The q,t-Catalan Numbers and the Space of Diagonal Harmonics, by Jim Haglund available online HERE. Additional resources can be found in Haiman's expository papers HERE and HERE.
During November we will be going over the proof of Shuffle conjecture by Carlsson and Mellit from their article HERE.
Below is an approximate schedule of the sections we plan to cover. I will try to keep the sections actually covered up to date.
