Description

Sometimes there are talks which do not fit into a series. This page serves to collect these talks, and their descriptions.

Castelnuovo's contractibility theorem

We will cover some aspects of the birational geometry of surfaces.

Greenlees–May duality

We will give an introduction to the homological algebra of formal schemes, by discussing the Greenlees-May duality over commutative noetherian rings.

For some background, see [1] and [2].
