## Number Theory seminar

### Hector Pasten, Queen’s University

#### “Modular forms, ABC and effective unit equation”

In this talk I will give a brief overview of a known approach to the ABC conjecture using modular forms. Then I will explain how this approach actually gives a partial result for the ABC conjecture and Szpiro’s conjecture. As a consequence, we will obtain a new effective proof of the finiteness of solutions to the S-unit equation, which does not involve linear forms in logarithms. This is joint work with Ram Murty.

### Michael Ka Shing Ng, Pure Mathematics, University of Waterloo

#### "Some aspects of Cantor sets"

For every positive, decreasing, summable sequence $a = (a_i)$, we can
construct a Cantor set $C_a$ associated with $a$. These Cantor sets
are not necessarily self-similar. Their dimensional properties and
measures have been studied in terms of the sequence $a$.

In this thesis, we extend these results to a more general collection

## Special colloquium

### Matthew Satriano, University of Michigan

#### "Stacky Resolutions of Singularities"

We will discuss a technique which allows one to approximate singular varieties by smooth spaces called stacks. As an application, we will address the following question, as well as some generalizations: given a linear action of a group G on complex n-space C^n, when is the quotient C^n/G a singular variety? We will also mention some applications to Hodge theory and to derived equivalences.
