Title: Twisted Conjugacy in Linear Groups over Polynomial and Laurent
Polynomial Algebras over Finite Fields
Abstract: Given an automorphism \phi : G \to G, one has the \phitwisted
conjugacy action of G on itself, given by g.x = g x\phi(g^{1}). The
orbits of this action are called the \phitwisted conjugacy classes. In
this talk, we will talk about twisted conjugacy in general and special
linear groups over F[t] and F[t, t^{1}] where F is any subfield of the
algebraic closure of \mathbb{F}_p. This is joint work with P. Sankaran.
Some new results by Shripad Garge and myself regarding twisted conjugacy
in other classical groups over \mathbb{F}_q[t] and \mathbb{F}_q[t,t^{1}]
will also be mentioned.

Title: Curves on K3 surfaces
Abstract: I will survey the recent completion (joint with ChenLiedtke) of
the remaining cases of the conjecture that a projective K3 surface
contains infinitely many rational curves. As a consequence of this along
with the BogomolovMiyaokaYau inequality and the deformation theory of
stable maps, I will explain (joint with Chen) how in characteristic zero
one can deduce the existence of infinitely many curves of any geometric
genus moving in maximal moduli on a K3 surface. In particular this leads
to an algebraic proof of a theorem of Kobayashi on vanishing of global
symmetric differentials and applications to 0cycles.
