"More on GLq(2) and SLq(2)"

Last week Hongdi constructed the Hopf algebra structure on GLq(2) and SLq(2).  I will discuss the natural coaction of these objects on the quantum plane kq(2).

"Finite and integral morphisms"

We will continue studying properties of finite and integral morphisms. We will use properties of algebra homomorphisms to prove that finite morphisms have finite fibers and that they are affine local on the target. We will also prove that integral morphisms are closed and we will study some examples. Time permitting we will introduce morphisms (locally) of finite type.
