“Recursive bound for Hilbert 17th problem”
Talk 1.

“Schnorr Randomness”
We will show that the notion of Schnorr randomness is consistent with intuition and leads to the desired statistical properties of random sets. Also we will prove the nice facts we have stated about the Schnorr test.

“Iterated Function Systems and the Inverse Problem”
We introduce iterated function systems, a subset of discrete dynamical systems. A few examples of self similar sets generated by such systems and motivation for the inverse problem of approximation are given. We show some work towards a practical solution of the inverse problem, speci

"Density of polynomials with squarefree discriminant"
The problem of the density of squarefree discriminant polynomials is an old one, being considered by many people, and the density being conjectured by Lenstra. A proof has been out of question for a

“Notions weaker than MLrandomness”
Though MartinL ̈of randomness is the central randomness notion we have discussed, one can address criticisms to the claim that this notion is the appropriate one by considering weaker and stronger randomness notions for sets. We will discuss weaker variants.

"Griffith's theorem and its applications"
In this talk, we will see how all of the machinery we built so far in this seminar, culminates in the statement of Griffith's theorem, which produces a well behaved description of the derivative of the period map in terms of the KodairaSpencer map. The power of this result will be explored through concrete examples. In particular, We will make our first encounter with a Torelli theorem.

“Xiaos Conjecture on Canonically Fibered Surfaces”
In 1988, Gang Xiao proposed a list of open problems on algebraic surfaces. Many of these remain open to this day. One of the problems concerns the maximal relative genus of a canonically fibered surface. In this talk, I will talk about my proof of this conjecture.

“A higher rank Selberg sieve and applications”
We present a general higher rank Selberg sieve and apply it to various questions in number theory. In particular, we improve upon a result of HeathBrown on almost prime ktuples. This is joint work with Professor Ram Murty.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
