Classical deformation theory

The concept of deforming a mathematical object, such as a variety, a bundle on a manifold, an algebra, or a complex structure, is very old. In many cases, infinitesimal deformations can be understood very well through homological methods.

In the first talk, we will give a gentle introduction to this topic, and explain in concrete examples the concept of functors on Artin rings. These capture the concept of infinitesimal deformations in a crucial way.
