Krull dimension for limit groups
Thursday November 8, 2007
11:30AM - 12:20PM
Speakers:
Larsen Louder
Abstract:
When fields are replaced by free groups, the notion of Krull dimension from
the theory of commutative rings has a natural interpretation as the supremum
of lengths of chains of proper epimorphisms of limit groups beginning with a
free group of fixed rank. I will sketch parts of the proof that it is finite
and give examples of the techniques and some inherent difficulties.
