This translates into removing a frozen variable from the initial quiver of the Grassmannian seed, but the actual variables change in a much more complicated way. Apologies for the slightly bad form in saying this, but you might find some of my papers on this with Launois helpful, and/or contact me by email if you like. (If you prefer, just ignore the word "quantum" in those papers.) | |
