Title: BorsukUlam Theorem
Abstract: The BorsukUlam theorem is a nice result in Algebraic Topology. It states that every continuous function from a sphere to a plane acts as antipode preserving for a point on sphere. In this talk we will discuss some basic definitions and concepts in Algebraic Topology. Then we will prove some theorems which will be helpful for the proof the BorsukUlam theorem. We will also discuss its generalisation to plane known as The Bisection theorem.

Title: Torsors on semistable curves and the problem of degenerations.
Abstract: This is part 2 of the previous talk. Let G be an almost simple,
simply connected algebraic group over the field of complex numbers. In
this talk I will discuss a basic question in the classification of
Gtorsors on curves, which is to construct a flat degeneration of the
moduli stack Gtorsors on a smooth projective curve when the curve
degenerates to an irreducible nodal curve. In this second part I will
discuss the problem addressed earlier in the setting of principal G
bundles for an almost simple algebraic group. We will recall the earlier
picture for the sake of continuity.
