Title: "Infinite words and fully residually free groups"
Date: 3:30pm Wednesday, September 18.
Room: 920 Burnside
Infinite words appear in group theory usually as a result of
going to the limit in some infinite process. I will discuss on
how one can represent elements of fully residually free groups by
infinite words of a very particular type. These words occur as a
limit in a series of approximations of a given fully residually
free group $G$ into a free group $F$. Such representations allow
one to treat elements in $G$ in the same manner as ordinary words
