“The Grigorchuk Group”
A finitely generated group is said to have intermediate growth if it has both superpolynomial and subexponential growth. In 1983, Grigorchuk answered the question asked by John Milnor: do groups with intermediate growth exist? We will discuss his answer to this question.

“The Turing Ordinal”
We present the notion of Turing Ordinal of a class of structures. The Turing Ordinal was introduced by Jockusch and Soare as a computability theoretic method for comparing complexities of classes of structures. We explain an example by Montalban of a class of structures that doesn’t have a Turing Ordinal.

"If you love a group, set it free."
The existence of algebraic topology (even if you claim to know nothing about it) should be enough to convince you that doing topology without group theory is difficult, frustrating, alcoholism inducing, and above all, a disservice to topology. In this talk I hope to convince you, at least for a moment, that thinking about groups while ignoring topology is a disservice to group theory.
