Basics of GIT, part II (continued) -- Bart Van Steirteghem
I will finish the overview of the basics of Geometric Invariant Theory and state the Hilbert-Mumford criterion

Variation of quotients: first examples, part I -- Anupam Bhatnagar
Following Marzia Polito [C. R. Acad. Sci. Paris Sér. I Math. 321 (1995), no. 12, 1577–1582, MathSciNet] we will describe the possible GIT quotients of the diagonal action of SL(2) on (P^1)^n.
