Polynomial automorphisms

The polynomial algebra in n variables is a fundamental object in algebra and geometry. Its symmetries (automorphisms) constitute a group whose properties were studied by many researchers, using techniques from algebraic groups, algebraic geometry, representation theory, commutative algebra, complex analysis and topology. This subject is related to a number of famous conjectures. In recent decades there have been important developments in this area; I will survey them in this talk.
